CP violation studies in B mesons
- Indiana U.
The four general purpose detectors on the Tevatron (CDF, D0) and LHC (Atlas, CMS) hadron colliders continue to make important measurements in the field of CP violation (CPV) in B hadron physics. The CDF collaboration presents new results in direct CPV of charmless B decays, providing world-leading measurements in b baryon decays, and finding evidence for non zero CPV in the decayB_s^0 -> K^-pi^+. The D0 Collaboration presents measurements of the semileptonic mixing asymmetries in B^0 and B_s^0 mesons, with the former having a precision exceeding the previous world average. All four experiments perform time-dependent angular analysis of the decay B_s^0 -> J/psiphi enabling the extraction of the lifetime difference DeltaGamma_s and the CPV phasephi_s^J/psiphi. In all cases, the results obtained are consistent with each other, and with the standard model predictions.
