64. New Physics searches in Heavy Flavor with ATLAS

William James Dearnaley (Lancaster University (GB))

Flavor Physics

parallel talk

Precision determinations of the flavor sector allow the search for indirect new physics signatures. At the forefront of these studies are the determinations of interference of new physics with known Df=1 and Df=2 processes. The ATLAS collaboration explores this area with competitive results measuring the CP violating phase phi_s from Bs->J/Psi phi decays and investigating rare B decays...

parallel talk

The differential cross section as a function of transverse momentum for the production of the $\Upsilon(nS)$ (n=1,2,3) states decaying into a pair of muons has been measured in pp collisions at $\sqrt{s}$ = 7 TeV using 4.9 fb$^{-1}$ of data collected by the CMS detector. The analysis selected events with dimuon rapidity $|y(\mu \mu)|< 0.6$, and the measurements cover dimuon transverse...

20. Flavour tagging at LHCb

Flavor Physics

parallel talk

The identification of the flavour of reconstructed Bd and Bs mesons at production is necessary for the measurements of oscillations and time-dependent CP asymmetries. The calibration and performance of opposite-side and same-side flavour tagging algorithms have been developed using simulated events and different flavour specific B decays with ~1 fb–1 of data collected in pp collisions at √s=7...

82. Strong interactions of leptons: lepton flavor-violating conversions in effective field theory

Alexey Petrov (Wayne State University)

Flavor Physics

parallel talk

Lepton flavor-violating processes offer interesting possibilities to probe New Physics at multi-TeV scale. Of these, processes like muon-to-electron conversion on nuclei or exclusive tau decays provide interesting interplay of particle and nuclear/hadronic physics effects. I will discuss lepton flavor-violating processes in the framework of effective field theory, emphasizing the role of...

15. Quarkonia and quarkonia-like spectroscopy at LHCb

Mr Bin Gui (Syracuse University (US), LHCb Collaboration)

07/05/2013, 15:00

Flavor Physics

parallel talk

The latest years have seen a resurrection of interest in searches for exotic states motivated by tantalizing observations by Belle and CDF. Using the data collected at pp collisions at 7 and 8 TeV by the LHCb experiment we present studies of the X(3872) properties.

47. New Physics in B->D^(*) tau nu_tau

Alakabha Datta (University of Mississippi)

Flavor Physics

parallel talk

The recent measurement of B->D^(*)tau nu_tau branching ratios are different from the SM predictions. This may be an indication of New Physics in these decays. We show how the measurement of various angular distributions can confirm and identify this New Physics. Special attention will be paid to triple product asymmetries that vanish in the SM.

30. Rare decays at LHCb

Marco Tresch (Universitaet Zuerich (CH))

07/05/2013, 15:30

Flavor Physics

parallel talk

Rare decays of beauty and charm hadrons and lepton flavour/number violating decays of tau leptons test the flavour structure of the underlying theory at the level of quantum corrections. They provide information on the couplings and masses of heavy virtual particles appearing as intermediate states. A review of recent results obtained by LHCb on these topics will be presented.
