New measurements on physics of $B$-hadrons in ATLAS experiment

Recent results on B-hadron physics in ATLAS are reviewed. A new measurement of CP-violating parameters in B$_{s}$ → J/ψφ decay is performed on full Run 1 statistics. Branching fraction BR(B$_{s}$ → μ$^{+}$μ$^{−}$) = (0.9$_{−0.8}^{+1.1}$ )×10$^{−9}$ is measured, below the Standard Model (SM) predicti...

Sumario:Recent results on B-hadron physics in ATLAS are reviewed. A new measurement of CP-violating parameters in B$_{s}$ → J/ψφ decay is performed on full Run 1 statistics. Branching fraction BR(B$_{s}$ → μ$^{+}$μ$^{−}$) = (0.9$_{−0.8}^{+1.1}$ )×10$^{−9}$ is measured, below the Standard Model (SM) prediction.
