23. Heavy flavour results in pp collisions at LHC with ALICE

Heavy Flavour Physics

Parallel Talk

The ALICE detector provides good performance and specific detector characteristics to study open heavy flavour hadrons and quarkonia, at central (|y| < 0.9) and forward (2.5 < y < 4) rapidity, thanks to its low momentum reach, particle identification capabilities and precise vertexing. Open heavy flavour production is studied using semileptonic decays to electrons and muons and, for open...

31. Heavy flavor production at ATLAS

Daniel Scheirich (University of Michigan (US))

The properties of b-hadrons have been studies in ATLAS, mainly through final states containing muon pairs. This talk will review the analyses completed, focussing on the results published recently (such as the limit on the branching fraction Bs to mu mu), and those currently approaching conclusion on lamda b (observation, mass and lifetime measurement) and Bs->J/psi phi (mixing and CP violation).

162. Recent results from BESIII

Haiping Peng (Univ. of Science & Tech. of China (CN))

With the world largest J/$\psi$, $\psi^{\prime}$ and $\psi^{\prime\prime}$ data samples collected with BESIII detector at the Beijing Electron Positron Collider(BEPCIII), a series charmonium meson spectroscopy and charmonium decay dynamics have been studies. In this talk, the study of spectroscopy will be introduced, and the new measured parameters of the spin-singlet charmonium states...

Heavy Flavour Physics

Parallel Talk

The potential for the discovery of flavour symmetric physics models at LHC is discussed. Considering flavour constraints on TeV scale new physics scenarios we motivate considering flavour symmetric extensions of the Standard Model, A systematic flavour symmetric approach to present and future collider anomalies is presented. The anomalous top quark forward backward asymmetry is used as...

83. Mixing and CPV in the B system

Sean Benson (University of Edinburgh (GB))

The determination of the CP-violating phase φs in B0s → J/ψφ decays is one of the key goals of the LHCb experiment. Its value is predicted to be very small in the Standard Model but can be significantly enhanced in many models of new physics. We present the world’s best measurement of φs and the first observation of a non-zero ∆Γs based on 1.0 fb−1 of data collected at LHCb during 2011. We...

84. CPV in hadronic B decays

Daniel Johnson (University of Oxford (GB))

The LHCb experiment is a general purpose forward spectrometer operating at the Large Hadron Collider, optimized for the study of B and D hadrons. LHCb collected 1.0 fb-1 of integrated luminosity during 2011 data taking, which provides unprecedented large samples of B hadron decays. These decays offer many complementary measurements of CP violation which probe directly or indirectly the...
