ATLAS B-physics overview

Prospects on measurements in the B system with the ATLAS detector at the LHC are reviewed. Measurements of sin 2β in the Bd0→J/ψKS0 channel and δγ in the Bd0→J/ψφ channel are described. Two approaches for extracting angles from the hadronic two-body decays Bd0→π+π− and Bs0→K+K− are presented. Studies of Bs0 oscillations and of rare decays B→μ+μ−(X) are also conducted.
