  1. 4. Flavor Physics at Belle II
    Francesco Tenchini
    20/05/2019, 14:00

    The Belle II experiment at the SuperKEKB energy-asymmetric $e^+ e^-$ collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The design luminosity of the machine is $8\times 10^{35}$ cm$^{-2}$s$^{-1}$ and the Belle II experiment aims to record 50 ab$^{-1}$ of data, a factor of 50 more than its predecessor. With this data set, Belle II will be able to measure...

  2. 8. Anomalies in b->s ll transitions (LHCb)
    Titus Mombächer
    20/05/2019, 14:30

    The concept of lepton universality, where the muon and tau particles are simply heavier copies of the electron, is a key prediction in the Standard Model (SM). In models beyond the SM, lepton universality can be naturally violated with new physics particles that couple preferentially to the second and third generation leptons. Over the last few years, several hints of lepton universality...

  7. 2. Aligned and Spontaneous Flavor Violation
    Daniel Egana-Ugrinovic (Stony Brook University)
    21/05/2019, 09:00

    We present a spurion setup called Spontaneous Flavor Violation (SFV) that allows for new physics couplings to quarks that are aligned with the Standard Model Yukawas, but do not necessarily share their hierarchies nor are family universal. We show that SFV naturally arises in theories where the quark family number and CP groups are spontaneously broken at a UV scale. In SFV extensions of the...

    Vladimir Savinov
    21/05/2019, 11:00

    The Belle II experiment at the SuperKEKB energy-asymmetric $e^+ e^-$ collider is a substantial upgrade of the B factory facility at KEK in Tsukuba, Japan. It aims to record a factor of 50 times more data than its predecessor. The experiment completed a commissioning run in 2018, and began full operation in early 2019. Belle II is uniquely capable of studying the so-called "XYZ" particles:...

  11. 10. CP violation and rare decays in charm decays with LHCb
    Angelo Di Canto
    21/05/2019, 11:30

    The LHCb experiment has collected large samples of decays of charmed hadrons, and has made measurements of CP violation and mixing parameters with world-leading precision. Recent results on charm physics at LHCb are presented.

  13. 13. Semileptonic and leptonic results from 2018 Belle II commissioning data
    Cao Lu
    21/05/2019, 14:00

    The Belle II experiment, located at the SuperKEKB accelerator complex near Tokyo in
    Japan, has started its 2019 run to collect collision events at large instantaneous
    luminosities. In this presentation we show first results from studying missing energy
    signatures, such as leptonic and semileptonic B meson decays: We report first studies
    on re-measuring important standard candle processes, such...

  14. 21. A four-dimensional form-factor fit to B->D*lnu with hadronic tagging from BaBar
    Biplap Dey
    21/05/2019, 14:30

    We present results on the first full 4-dimensional angular analysis of B->D*lnu, using the e+e- collision dataset collected by the BaBar experiment at the Y(4S) resonance. One B meson from the Y(4S)->BBbar decay is fully reconstructed in a hadronic decay mode which constrains the kinematics and provides a precise determination of the neutrino momentum vector. We extract the underlying hadronic...

  18. 6. BSM Physics with Kaon Decays at NA62
    Rainer Wanke
    21/05/2019, 17:00

    The NA62 experiment at CERN SPS was designed to measure BR(K+ -> pi+ nu nu-bar) with in-flight decays, a novel technique for this channel. NA62 took its first physics data in 2016, reaching sensitivity to the decay at the Standard Model BR. The experiment collected 10 times more statistics in 2017 and a similar amount of data is expected from the 2018 run. The result on K+ -> pi+ nu nu from...

  24. 19. Charm-loop effect in B->K(*)ll decays beyond leading twist
    Nico Gubernari (technische universität münchen)
    22/05/2019, 12:00

    We revisit soft gluon contributions to the "charm loop" effect in rare $B\to K^{(*)}ll$ decays, which is a large systematic uncertainty in the interpretation of the $b$-anomalies. Since these contributions are dominated by long-distance effects and are resistant to factorization attempts, we employ the method of light-cone sum rules to compute the relevant hadronic matrix elements. Our...

    Mirco Dorigo
    22/05/2019, 14:30

    Precision measurements of CP violating observables in b hadron decays are powerful probes to search for physics effects beyond the Standard Model. The most recent results on CP violation in the decay, mixing and interference of b hadrons obtained by the LHCb Collaboration will be presented, with particular focus on results obtained exploiting the data collected during the Run 2 of LHC. These...

  27. 3. High-pT Signatures in Vector-Leptoquark Models
    Michael Baker (University of Zurich)
    22/05/2019, 15:00

    We present a detailed analysis of the collider signatures of TeV-scale massive vector bosons motivated by the hints of lepton flavour non-universality observed in $B$-meson decays. We analyse three representations that necessarily appear together in a large class of ultraviolet-complete models: a colour-singlet ($Z'$), a colour-triplet (the $U_1$ leptoquark), and a colour octet ($G'$). Under...

  28. 7. Anomalies in semileptonic B decays (LHCb)
    Annarita Buonaura
    22/05/2019, 16:00

    Rare decays are powerful probes for Physics beyond the Standard Model (SM), as new particles can have a large impact on physics observables. Recent results on lepton universality tests and measurements of branching fractions and angular distributions of rare b->sll decays have shown tensions with the SM predictions. A review of the latest lepton universality tests in semileptonic b →clν ...

  29. 20. New Physics in b → c τ ν: From R(D), R(D*) to Polarisation Observables, B_c → τ ν, and Λ_b → Λ_c τ ν
    Monika Blanke (Karlsruhe Institute of Technology)
    22/05/2019, 16:30

    In this talk I review the status of new physics in b→cτν transitions in the EFT framework of dimension-six operators, including the very recent Belle results. The fit results, including the recent measurement of FL(D*), are presented for all one- and two-dimensional scenarios resulting from the tree level exchange of a single new particle. Particular emphasis is put on the constraint from the...
