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 B0s, the branching fraction B(B0s→μ+μ−)=(0.9+1.1−0.8)×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.}, publisher = {Springer International Publishing}, keywords = {Decays}, keywords = {Luminosity}, keywords = {Proton collisions}, keywords = {Atlas detector}, keywords = {Hadron}, title = {Study of the rare decays of B0s and B0 into muon pairs from data collected during the LHC Run 1 with the ATLAS detector}, doi = {10.1140/epjc/s10052-016-4338-8}, author = {Aaboud, M. and Aguilar Saavedra, Juan Antonio and Atlas Collaboration}, }
