Study of the rare decays of Bs0 and B0 into muon pairs from data collected during the LHC Run 1 with the ATLAS detector

A study of the decays Bs0→μ+μ-$$B^0_s \rightarrow \mu ^+\mu ^-$$ and B0→μ+μ-$$B^0 \rightarrow \mu ^+\mu ^-$$ has been performed using data corresponding to an integrated luminosity of 25 fb-1$$^{-1}$$ of 7 and 8 TeV proton–proton collisions collected with the ATLAS detector during the LHC Run 1
