Measurement of the B0s→μ+μ− branching fraction and effective lifetime and search for B0→μ+μ−decays.
<p>A search for the rare decays B0s→μ+μ− and B0→μ+μ− is performed at the LHCb experiment using data collected in pp collisions corresponding to a total integrated luminosity of 4.4 fb−1. An excess of B0s→μ+μ− decays is observed with a significance of 7.8 standard deviations, representing the...
