Search for the rare decays B0s → μ+ μ− and B0 → μ+ μ-

A search for the decays B0s →μ+μ− and B0→μ+μ− is performed with about 37 pb−1 of pp collisions at √ s = 7 TeV collected by the LHCb experiment at the Large Hadron Collider at CERN. The observed numbers of events are consistent with the background expectations. The resulting upper limits on the branc...

Descrição
Resumo:A search for the decays B0s →μ+μ− and B0→μ+μ− is performed with about 37 pb−1 of pp collisions at √ s = 7 TeV collected by the LHCb experiment at the Large Hadron Collider at CERN. The observed numbers of events are consistent with the background expectations. The resulting upper limits on the branching ratios are B(B0s →μ+μ− ) < 5.6 × 10−8 and B(B0 →μ+μ− ) < 1.5 × 10−8 at 95% confidence level
