Joe Mohr12/10/2009, 09:05The South Pole Telescope (SPT) is currently being used to survey the cosmic microwave background in search of galaxy clusters, the most massive collapsed structures in the Universe. A small fraction of the cosmic microwave photons that pass through these clusters scatter with the reservoir of high energy electrons produced during the cluster formation. These interactions lead to a distortion...Go to contribution page

Ralf Kelzenberg12/10/2009, 10:30Samples of galaxies have already been used in the Sloan Digital Sky Survey (SDSS) and the two degree field survey (2dF) to calculate the power spectrum of the baryonic-, and thus indirectly, the dark matter in the universe. However, being at low redshift, non-linear effects are severely limiting the value of the data by mixing mode information. Lyman-Alpha Emitters (LAEs), being at high...Go to contribution page

Aleksi Halkola12/10/2009, 11:00In gravitational lensing the light rays from sources behind the massive body are deflected due to the distortion of space-time around massive bodies as described by general relativity. In an astronomical context this leads to distortions in the shapes of observed images of, for example, galaxies behind other galaxies and galaxy clusters. These distortions can be used to estimate the amount and...Go to contribution page

Laura Fabbietti (TUM)12/10/2009, 13:30Recently several experiments with Kaon beams, aiming to study the existence of kaonic bound states, have been carried out. Along with these experimental approaches, our Excellence Cluster Universe group has developed in the last two years a new method, based on proton induced reactions at intermediate kinetic energies (E=2-4 GeV), to approach the experimental quest of such states. In...Go to contribution page

Federica Petricca (MPP)12/10/2009, 14:00The CRESST cryogenic direct Dark Matter search is located in the Gran Sasso underground laboratories. CaWO4 crystals have been used as scintillating targets for WIMP interactions. Each crystal is operated as a cryogenic calorimeter in combination with a second cryogenic detector used to measure the scintillation light produced in the target crystal. For each particle interaction, the...Go to contribution page

Andre Hoang (MPP)12/10/2009, 14:30There are a number of conceptual questions concerning the measurement of the top quark mass that are still unanswered, but which are important given the current top mass uncertainty of only 1.3 GeV. These questions are related to color neutralization and the finite lifetime of the top quark. Some of these problems can be addressed in the framework of e+e-colliders. I explain what these...Go to contribution page

Frank Steffen (MPP)12/10/2009, 15:00Supersymmetry (SUSY) is a well-motivated extension of the Standard Model which comes with compelling candidates for dark matter. In fact, the Large Hadron Collider may give us a first opportunity to test SUSY directly in the laboratory. In addition to collider experiments, the early Universe offers complementary ways to probe new physics. This talk will review restrictions on SUSY models...Go to contribution page

Katharina Fierlinger (TUM)12/10/2009, 16:00The aim of this project is to shed light on the impact of massive stars on the interstellar medium (ISM) in their surroundings. A good example of a region revealing such interactions between stars and the ISM is the Orion/Eridanus Superbubble (OES), a cavity blown by stellar winds and supernova explosions. This region has the advantage of being well observed. It's interaction with the local...Go to contribution page

Frank Simon13/10/2009, 09:00Calorimeters, detectors that measure the energy of particles by total absorption, play a crucial role in modern particle physics experiments. Hermetic coverage of the interaction and precise measurement of the total energy in the events is crucial to identify new physics involving stable, weakly interacting particles which can only be detected by missing transverse energy in the overall...Go to contribution page

Magdalena Larfors (LMU)13/10/2009, 10:30The many different ways to compactify string theory lead to a large collection of effectively four-dimensional vacua, commonly known as the string theory landscape. In this talk, I will discuss some features of the vacua in the landscape. After a brief introduction to the compactifications that give rise to the vacua, I will turn to the discussion of their stability. I will discuss different...Go to contribution page

Andres Collinucci (LMU)13/10/2009, 11:00Fourteen years ago, string theory underwent a major paradigm shift when techniques were developed to study the theory in its strongly coupled regime. More specifically, the introduction of D-branes and eventually M-theory opened up windows that relate the different versions of string theory, in different corners of its parameter space. A year after the idea of M-theory was conceived, Vafa...Go to contribution page

Jacopo Ghiglieri13/10/2009, 11:30In this talk I will briefly introduce the subject of finite temperature Quantum Chromodynamics and its connection to the structure of the early universe and the heavy ion collision experiments at RHIC (BNL) and in the future at the LHC. In these collisions a new state of matter, called the Quark-Gluon Plasma, is claimed to be formed. I will introduce some of the theoretical tools for the...Go to contribution page

Marie-Helene Genest (LMU)13/10/2009, 13:30In this talk, we will review the current strategies to search for supersymmetry (SUSY), a well-motivated extension of the Standard Model, in the ATLAS detector at the Large Hadron Collider. The talk will cover the search channels based on missing transverse momentum from undetected neutralinos and multiple jets, assuming a SUSY with R-parity conservation. The discovery reach in early data will...Go to contribution page

Hubert Kroha (MPP)13/10/2009, 14:00Searches for inclusive signatures of the production of supersymmetric particles are among the first physics studies to be performed by the experiments at the Large Hadron Collider (LHC). The large backgrounds from Standard Model processes have to be strongly suppressed and well understood before the discovery of new physics can be claimed. Since both the knowledge of the detector performance...Go to contribution page

Jean-Côme Lanfranchi (TUM)13/10/2009, 14:30The largest fraction of matter density in the Universe is Dark Matter (~23%), which could be present in the form of WIMPs (= Weakly Interacting Massive Particles). A highly favoured candidate as WIMP is the neutralino predicted by SUSY theories in the frame of the Minimal Supersymmetric Standard Model (MSSM). Direct experimental detection of WIMPs is expected to be possible via nuclear recoil...Go to contribution page

Marco Baldi (MPA)13/10/2009, 16:00The strong evidence in favor of an accelerated expansion of the Universe demands for an explanation of the nature of the dark energy responsible for it. Besides the simplest option of a cosmological constant, which suffers of a series of fundamental problems, several models of dynamic dark energy have been proposed and investigated in the last decade. Among such models, a particular attention...Go to contribution page

Michael Hecht (LMU)14/10/2009, 10:30Topological String theory is a way of accessing the geometric information encoded in a full-fledged string theory compactification. After giving a short introduction to topological string theory I show how it can be used to compute certain non-perturbative terms in the low-energy effective action of a large class of string compactifications with D-branes.Go to contribution page

David Straub (TUM)14/10/2009, 11:00Supersymmetric theories belong to the most attractive extensions of the standard model. While the LHC might be able to directly produce supersymmetric particles by pushing the "high-energy frontier", quark and lepton flavour physics, pushing the "high-precision frontier", provide a complementary tool to shed light on the nature of new physics. I will discuss the predictions for observables...Go to contribution page

Lise Christensen14/10/2009, 13:30Intervening Damped Lyman alpha systems (DLAs) detected in quasar spectra contain the majority of the neutral gas mass at redshifts z>2. Generally, DLAs have metallicities between one and ten percent solar, which is lower than the metallicities of high redshift galaxies from luminosity selected samples. This discrepancy can be explained by selection effects from extended gaseous disks around...Go to contribution page
