Description
Recent results from the ATLAS experiment on the B_c production and decays will be presented. The measurement of the ratios of the B_c+ and B+ production cross sections in proton-proton collisions at 8 TeV will be discussed.
The ATLAS experiment has performed accurate measurements of mixing and CP violation in the neutral B mesons, and also of rare processes happening in electroweak FCNC-suppressed neutral B-mesons decays. This talk will also focus on the latest results from ATLAS, such as rare processes: B^0_s → mu mu and B^0 → mu mu; and CPV in the B_s^0 —> J/psi phi decays. In the latter, the Standard Model predicts the CP violating mixing phase, phi_s, to be very small and its SM value is very well constrained, while in many new physics models large phi_s values are expected. Latest measurements of phi_s and several other parameters describing the B_s^0 —> J/psi phi decays will be reported.
