Mr Jack Wimberley (University of Maryland, College Park)05/05/2015, 16:30parallel talkThe LHCb collaboration has recently released a number of new and updated measurements of the CP violating angles β and φs using the full 2011 and 2012 datasets. These CP violating parameters, which are sensitive to possible BSM physics, are observable in the interference between mixing and b->ccs decays of B and Bs mesons, respectively. LHCb has measured sin(2β) in an analysis of B -> J/ψ KS...Go to contribution page

Rodrigo Alonso (UC San Diego)05/05/2015, 16:45parallel talkFlavor physics offers a formidable window into new physics. In particular rare B-meson decays have received a great share of attention due to recent anomalous measurements. The customary Effective Field Theory scheme parametrizes deviations from the Standard Theory at the B meson scale with operators invariant under electro-magnetism and the strong interactions. However, if the scale of...Go to contribution page

Daniel Patrick O'Hanlon (University of Warwick (GB))05/05/2015, 17:00parallel talkDecays of b-hadrons to suppressed ‘charm-less’ final states are an attractive avenue to test the Standard Model, as they typically proceed via 'penguin' loop diagrams where new physics may enter virtually, and are also sensitive to CP violation via the interference between these penguin processes and the tree-level processes. We present the latest studies of such decays on the Run 1 dataset of...Go to contribution page

Shanmuka Shivashankara (University of Mississippi)05/05/2015, 17:15parallel talkAt present, there are several hints of lepton flavor non-universality. The LHCb Collaboration has measured $R_K$≡$B(B^+→K^+μ^+μ^−)/B(B^+→K^+e^+e^−)$, and the BaBar Collaboration has measured $R(D^{(∗)})$≡$B(\bar{B}→D^{(∗)+}τ^−\bar{ν}_τ)/B(\bar{B}→D^{(∗)+}ℓ^−\bar{ν}_ℓ)$ $(ℓ=e,μ)$. In all cases, the experimental results differ from the standard model predictions by 2-3$σ$. Recently, an...Go to contribution page

Mohammad Ahmady (Mount Allison University)05/05/2015, 17:30parallel talkWe use the light front wavefunction predicted by holographic anti–de Sitter/Chromodynamics (AdS/QCD) for $K^*$ vector meson to obtain the form factors for exclusive dileptonic rare $B \to K^* \mu^+ \mu^-$ decay. Consequently, the differential decay rate, isospin and forward-backward asymmetry distributions for this transition mode are obtained and compared with the latest available...Go to contribution page

Dr alessandro bertolin (LHCb - INFN (Padova))05/05/2015, 17:45parallel talkThe weak phase $\gamma$ is one of the least well-determined CKM parameters. It can be measured using time-independent decay rates, such as those of $B^+ \to D K^+$ with $D \to K^0_s h h$, or by time-dependent studies, as in $B^0_s \to D_s^{\mp} K^{\pm}$ decays. The precise determination of $\gamma$ is one of the most important goals of LHCb. Several recent time-independent and...Go to contribution page

Steffen Maeland (University of Bergen (NO))05/05/2015, 18:00Flavorparallel talkLatest results in the ATLAS programme of searches and precision measurement of heavy hadrons are presented. It includes observation of an excited B_c(2S) state, measurement of the B_c meson decays, as well as new decay modes of b-hadrons and search for New Physics signatures in processes that are naturally suppressed in the Standard Model. We present the latest search for rare B_s ->...Go to contribution page
