      HL RU-A: Searches for dark matter at the LHC 25m New Seminar Room, 1.1.18abG

      Although measurements confirm the Standard Model of particle physics
      (SM) to high precision until now, multiple shortcomings motivate the
      search for physics beyond the SM. For example, the SM does not offer a
      candidate particle to explain (cold) dark matter (DM). A comprehensive
      search program is carried out by direct and indirect detection
      experiments, but also at particle colliders like the Large Hadron
      Collider (LHC) using proton-proton collisions.
      As DM particles are not electromagnetically or strongly interacting,
      they cannot directly be detected in the detectors at the LHC. Instead,
      the presence of DM particles would lead to missing momentum in the
      transverse plane to the proton-proton collision (ETmiss), which is thus
      an important signature in these searches. DM particles could be produced
      in proton-proton collisions directly through a mediator particle linking
      SM particles to DM particles, or could be produced in the decay of other
      new particles, like supersymmetric particles.

      This talk presents recent highlights of these searches at the ATLAS
      detector at the LHC, with major involvements of the LMU and MPP groups.
      The results will be placed in context to (in)direct detection
      experiments to discuss the complementarity of the different searches.

      The last years have seen a revolution in Optical/Infrared Interferometry. The GRAVITY instrument at the VLTI is now routinely providing milli-arcsecond resolution imaging and micro-arcsecond astrometry, for objects which are order of magnitudes fainter than what has been possible before. In our presentation we give an overview of the GRAVITY discoveries in Galactic Center Black Hole and Active Galactic Nuclei (AGN). Among others we will present the tests of Einstein's theory of general relativity and its underlying principles from precise stellar orbit measurement, and the discovery of highly relativistic, circular motion of hot gas close to the innermost circular orbit around SgrA. Especially the time resolved astrometry and the polarization measurements of the flaring SgrA shed new light on the mechanisms driving the accretion / outflow of black holes. We further present some of the GRAVITY results on AGNs, including the image of the hot dust around NGC 1068, the sizes and structure for a first sample of AGNs, and the spatially resolved rotation of the broadline region (BLR) of quasars. We will round of the talk by reporting on the ongoing upgrades and plans towards GRAVITY+ all sky milli arcsecond optical interferometric imaging.

      Ongoing and future galaxy surveys are providing a cartography of the distribution of matter in the universe over large volumes and across long spans of time. This allows us to learn about cosmology through the study of the formation and evolution of structures. In this talk I will outline the potential constraining power and the challenges posed by the analysis of large scale structure data.

      The JUNO (Jiangmen Underground Neutrino Observatory) project in China is aiming for high precision measurements in the field of low energy neutrino and astroparticle physics. Main goals are the determination of the neutrino mass ordering and the accurate measurement of neutrino oscillation parameters by high resolution spectroscopy of reactor neutrinos. In addition solar neutrino spectroscopy, the search for the diffuse Supernova neutrino background (DSNB) and the search for proton decay are main goals of JUNO. In case of a Supernova burst in our local group JUNO would measure a strong neutrino flavour dependent signal at high statistics. The JUNO detector will consist of an acrylic sphere with 35m in diameter, holding 20,000 tons of a liquid scintillator, which acts as neutrino target. In the talk I will review the main scientific topics of JUNO and I will present the status of the experimental set-up.

      Radial drift of dust particles is a long-standing problem in planet formation. Due to its pressure gradient, gas in protoplanetary disks is orbiting the central star with sub-Keplerian velocities. Dust particles, on the other hand, try to orbit with Keplerian velocities. They feel a headwind from the gas, lose angular momentum, and drift towards the star on short timescales.

      Observations of protoplanetary disks, however, show more dust around protostars than models of circumstellar disks with radially drifting dust particles would predict. As a solution to this problem, pressure bumps have been proposed in the past, that can trap dust particles and prevent them from drifting towards the star.

      And indeed, recent high resolution observations of disks with ALMA show dust trapped in ring-like sub-structures. As a surprising result, the DSHARP survey of disks showed, that all of their analyzed rings have optical depths between 0.2 and 0.5 – none of the rings is fully optically thick.

      Since dust traps are thought to be locations of planet formation by converting dust pebbles into planetesimals, this can yield as an explanation for the peculiar optical depths: dust has been transformed into large bodies, reducing the optical depths in the rings.

      To test this scenario in more detail, we implemented a simple method of planetesimal formation into our dust growth and disk evolution code DustPy. We found that planetesimal formation in dust traps could indeed explain the seemingly fine-tuned optical depths, that are observed in the rings of protoplanetary disks.

      I present the results of a re-analysis of anisotropic galaxy clustering measurements from the Baryon Oscillation Spectroscopic Survey (BOSS), demonstrating that they provide independent cosmological constraints that are comparable to other low-redshift probes. These data thus represent an independent tool to probe the cosmology of the low-redshift Universe. I quantify the agreement between BOSS and the cosmic microwave background from Planck 2018, showing that the two data sets are consistent within a flat ΛCDM cosmology.

      Recently, several massive structures at redshifts as high as z=8 have been discovered, many of which are thought to be the progenitors of todays most massive clusters of galaxies. The star formation rates observed in these "protoclusters" is much higher than expected, and the origin of these extreme star bursts is currently a matter of heavy debate. Using the power of the state-of-the-art hydrodynamical cosmological simulation suit Magneticum Pathfinder, I study the formation of protocluster like structures at redshifts 4-5, and the evolution of such structures to present-day. I will present starformation and gas properties of the protocluster galaxy members in comparison to state-of-the-art observations, as well as kinematical properties of such very early galaxies, and I will demonstrate what we can learn from the combined approach of simulations and observations about cosmology, the build-up of structures, and the laws of star formation in the early phases of our Universe.

      The results of one-dimensional stellar evolution models depend on recipes for convection, mixing, and diffusion deep inside the stars. Three-dimensional simulations are required to make more reliable models that are independent of the choice of these recipes. In addition, the three-dimensional models show asymmetries which may aid the subsequent neutrino driven explosion. We have simulated seven minutes of oxygen burning phase of a massive star (18.88 $\rm M_{\odot}$) prior to collapse. The initial model is unstable against convection and with time we observe the development of large scale modes in the flow. The behavior of convection is quite different in such a system. Convective eddies bring lighter elements into the inner burning zone where they can be burnt episodically at a much faster rate which further powers convection leading to large scale flows. This is an example of a “reactive-convective” hydrodynamic system. In this talk, I will describe the results of our simulations, and the physical picture of convective-reactive flows which may develop during the last burning stages of a star.

      The present tensions between theory predictions and measurements in
      semileptonic decays of bottom hadrons have sparked widespread interest
      as possible indicators of Physics beyond the Standard Model. At the same
      time, these tensions motivate thorough checks of the Standard Model
      predictions, in terms of both methods and inputs. In this presentation I will
      discuss recent and ongoing analyses of the hadronic matrix elements
      emerging in b -> c tau^-\bar \nu transitions, and their impact on the
      SM predictions of the lepton-flavour universality ratios R(D^(*)) and on

      Information field theory (IFT) describes probabilistic image reconstruction from incomplete and noisy data. Based on field theoretical concepts IFT provides optimal methods to generate images exploiting all available information. IFT algorithms can be regarded as interpretable neural networks, with a design determined by the physical knowledge on the observed system. Applications in astrophysics are galactic tomography, gamma- and radio- astronomical imaging, and the analysis of cosmic microwave background data.

      The theoretical interpretation of dark matter experiments is hindered by uncertainties of the dark matter density and velocity distribution inside the Solar System. In order to quantify those uncertainties, we present a parameter that characterizes the deviation of the true velocity distribution from the Maxwell-Boltzmann form. This allows us to bracket, in a model independent way, the impact of the astrophysical uncertainties on the interpretation of esults from direct detection experiments and/or neutrino telescopes. In order to stress the importance of astrophysical uncertainties, we discuss a concrete example by determining the impact of substructure on local dark matter searches.

      Motivated by the holographic duality between a certain class of three-dimensional superconformal theories and type IIB Supergravity on anti de-Sitter warped backgrounds, I will present a new mechanism through which the lowest-lying graviton in the four dimensional anti de-Sitter bulk can become slightly massive. This is a string theory embedding of massive anti de-Sitter gravity and it will be shown that it emerges as a special limit of a corresponding bi-gravity theory. The obtained mass formula depends on parameters of the geometry of the warped background as well as from the variation of the dilaton field. The analysis is extended to the study of manifolds which allow for
      multiple massive gravitons.

      Two phenomena contribute to correlating galaxy shapes across the Universe: the deviation of photons from a straight path due to the spacetime curvature ("gravitational lensing”), and tidal interactions (“intrinsic alignments”). Modelling both accurately is crucial to obtaining unbiased constraints on the cosmological model from forthcoming surveys, particularly in the context of elucidating the origin of accelerated expansion of the Universe. In this talk, I will cover recent advances in our understanding of the intrinsic alignments of galaxies. While these alignments are typically regarded as a contaminant to weak gravitational lensing, I will also discuss how they might become a cosmological probe in their own right in the near future.

      eROSITA was successfully launched on board the Russian-German "Spectrum-Roentgen-Gamma" (SRG) satellite on July 13th 2019. With this instrument we want to: 1) detect the hot intergalactic medium of more than 100,000 galaxy clusters and groups and the hot gas in filaments between clusters to map out the large scale structure of the Universe for the study of cosmic structure evolution; 2) detect systematically all obscured accreting Black Holes in nearby galaxies and many (up to 3 Million) new, distant active galactic nuclei, and 3) study in detail the physics of galactic X-ray source populations, like pre-main sequence stars, supernova remnants and X-ray binaries. In my talk I will report on the actual performances of the instrument in comparison with the expectations before launch. In particular, I will highlight how eROSITA is already changing what we know about the hot and energetic Universe.

      AWAKE is an experimental program that uses a 400 GeV proton bunch from CERN SPS to drive GV/m scale wakefields in a photoionized rubidium plasma with a density on the order of 10^14 /cm^3. Since the proton bunch's longitudinal scale is greater than 100 times the plasma wavelength, the experiment relies on seeded self modulation (SSM) of the proton bunch to effectively drive wakefields. In 2018, AWAKE completed its first phase, AWAKE Run 1, in which proton bunch SSM and the acceleration of externally injected electrons were demonstrated. The discussion includes the physics of plasma wakefields and SSM, followed by the experimental results of AWAKE Run 1, and finally the future with AWAKE Run 2 and beyond.

      X-ray emission from the hot gas contained in galaxy clusters has long been established as a reliable method to selected large and clean samples of galaxy clusters. Utilising such samples to constrain the density and amplitude of fluctuation of matter in the Universe, as well as the evolution of Dark Energy, however, require to overcome several observational challenges as well as to control several systematic effects.
      First, I review the established modelling framework to extract cosmological information from cluster catalogues and present the expected performance of eROSITA as a cluster finding tool. After that, I will present recent and ongoing efforts to control the dominant systematic effects plaguing cluster cosmology, ranging from mass calibration over optical confirmation and redshift estimation to the characterisation of the X-ray selection function. Finally, I will present novel techniques that allow one to empirically validate cluster cosmological results.

      After several years of construction, the Belle II experiment at the SuperKEKB accelerator in Tsukuba, Japan has successfully started taking data for physics analyses this year. With a sample of 50 times more e+e- collision events than its predecessor to be collected in the next few years, Belle II will be able to search for physics beyond the standard model with unprecedented precision in many decay channels of B mesons, charm hadrons, and tau leptons. The status of the experiment and first performance measurements will be presented.

      Production of heavy quarkonia is a multiscale problem that is sensitive to different behaviors of strong interaction at various distances. Effective field theory methods such as pNRQCD provide factorization formalisms that let us separate quantities that depend on different scales. Based on the pNRQCD factorization formalism, we study the production cross section of heavy quarkonia in lepton and hadron colliders.

      Pioneering studies by the ALICE Collaboration demonstrated the potential of employing femtoscopy to investigate and constrain baryon-baryon and baryon-meson interactions with unprecedented precision. This kind of interactions is particularly interesting since it is closely connected to the physics of neutron stars. In particular, one of the plausible hypotheses about the content of neutron stars is that neutrons and hyperons might be contained in the core. To obtain a better understanding of the composition of these objects, a detailed knowledge of the interaction of the constituents becomes mandatory. This kind of analyses is complementary to previous attempts to study the interaction with scattering experiments, which are difficult to conduct due to the instable nature of hyperon beams.

      In this contribution, we present measurements of the ALICE Collaboration in pp collisions at √s = 7 and 13 TeV and p–Pb at √s$_{NN}$ = 5.02 TeV. The statistics of RUN 2 data provide a higher precision in the analysis of the p-p, p-Λ and Λ-Λ correlations, and additionally make it possible to probe the interaction of more exotic pairs such as p-K, p-Ξ, p-$\Omega$ and p-$\Sigma^{0}$. Newly developed analysis tools allow comparing the measured correlation function between the particle pairs of interest to theory predictions using either potentials or wave functions as input. This enables us to verify chiral and lattice calculations of the interaction and to constrain the corresponding scattering parameters.

      The cosmic large-scale distribution of matter encodes a wealth of information about our Universe. In this talk, I will show results on the observational signatures expected from galaxy formation processes, such as black hole feedback, as well as from primordial Universe physics during Inflation. These results were obtained with the aid of "Response Functions", which describe rigorously the complicated dependence of galaxy formation on the environment in which they form. These functions were measured for the first time with a technique called "Separate Universe Simulation" using the IllustrisTNG model, a state of the art hydrodynamical simulation code of cosmological galaxy formation. The results I will show pinpoint a concrete way to use galaxy clustering and gravitational lensing measurements to constrain the primordial Universe, as well as how galaxies form across time.

      The Higgs boson discovery in the year 2012 at the Large Hadron Collider (LHC) has been so far the greatest success of the ATLAS and CMS collaborations [arXiv:1207.7214]. Since then multiple studies have been performed to deter- mine whether the properties of this particle (such as CP state, spin, mass and coupling to bosons and fermions) are compatible with the predictions of the Standard Model (SM) or not.
      All measurements that have been done so far on the Higgs boson properties seem to verify the SM predictions. However, several questions related to the Higgs boson are still unanswered. One of which is whether the coupling of the Higgs to other bosons and fermions correspond to the predictions of the Standard Model or whether deviations with respect to the SM can be observed.
      With the large data set that have been collected by the ATLAS and CMS experiments during the complete Run-2 of the LHC, it is possible to measure differential and fiducial production cross sections with a high precision and interpret them in the context of effective field theories. In these approaches, the SM Lagrangian is supplemented by additional higher-dimension operators. Some of these new operators encode new structures for the interaction between the Higgs boson and the SM particles, which can modify the shapes of kinematic distributions. It is assumed that the new interaction terms in the Lagrangian are the low-energy manifestation of new physics that exists at an energy scale that is much larger than the partonic centre-of-mass energies being probed.
      This talk gives an experimental overview of the latest Higgs boson prop- erty measurements at the LHC experiments based on effective field theory ap- proaches.

      It is widely accepted that nucleic acids were crucial for the emergence of primitive life on Earth 3.5 – 4 billion years ago. However, geochemical conditions on early Earth must have differed greatly from the constant internal milieus of today's cells where modern biocatalysis takes place. Our research focuses on the activity of catalytic RNA polymers (ribozymes) under extreme and/or unusual conditions that may relate to prebiotic environments. In particular, we are interested in how environmental effects on early Earth might have driven crucial processes such as self-replication or the formation and proliferation of early protocells. As part of the Origins cluster, we are also interested if putative conditions on exoplanets in the habitable zone are compatible with nucleic acid-based biocatalysis.

      Subsequent to the Moon’s formation, late accretion to the terrestrial planets strongly modified the physical and chemical nature of their silicate crusts and mantles. Here, dynamical N-body and Monte Carlo simulations are combined to determine impact probabilities, impact velocities, and expected mass augmentation onto the terrestrial planets from three sources: planetesimals left over from primary accretion, asteroids from the hypothetical E-belt, and comets arriving from the outer Solar System. I present new estimates of the amount of cometary material striking the terrestrial planets in an early (ca. 4480 Ma) episode of planetesimal-driven giant planet migration (Mojzsis et al. 2019; Brasser, Werner & Mojzsis 2019). The Moon and Mars suffer proportionally higher cometary accretion than Venus and Earth at late accretion. The background mass addition from small leftover planetesimals to Earth and Mars is far less than independent estimates based on geochemical tracers. This supports the theory that both planets were struck by single large bodies that delivered most of their terminal mass augmentation since primary accretion, rather than a throng of smaller impactors. I also present new fits to the impact chronologies valid from 4500 Ma to ca. 3700 Ma by which time the low number of planetesimals remaining in the dynamical simulations causes the impact rate to drop artificially. This temporal interval in solar system evolution, termed late accretion, thermally and chemically modified solid planetary surfaces and may have impeded life’s emergence on the Hadean (pre-3.85 Ga) Earth. I will conclude the presentation with amended global 3-D thermal analytical bombardment models derived from our new impact mass-production functions to show that persistent niches for prebiotic chemistry on the early Hadean Earth could endure late accretion a mere 170 Myr after the start of the solar system (Benner et al. 2019).
