Abstract

A study of the decays Bs0→μ+μ- and B⁰→ μ⁺μ^- has been performed using data corresponding to an integrated luminosity of 25 fb^{- 1} of 7 and 8 TeV proton–proton collisions collected with the ATLAS detector during the LHC Run 1. For the B⁰ dimuon decay, an upper limit on the branching fraction is set at B(B⁰→ μ⁺μ^-) < 4.2 × 10 ^{- 10} at 95 % confidence level. For Bs0, the branching fraction B(Bs0→μ+μ-)=(0.9-0.8+1.1)×10-9 is measured. The results are consistent with the Standard Model expectation with a p value of 4.8 %, corresponding to 2.0 standard deviations.
