Search for the FCNC’s $B^0_s \to µ^+µ^−$ and $B^0 \to µ^+µ^−$ with the LHCb spectrometer
A search for the decays $B^0_s \to µ^+µ^−$ and $B^0 \to µ^+µ^−$ is performed with about $37 pb^{−1}$ of pp collisions at $\sqrt{s}$ = 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 resul...

| description | A search for the decays $B^0_s \to µ^+µ^−$ and $B^0 \to µ^+µ^−$ is performed with about $37 pb^{−1}$ of pp collisions at $\sqrt{s}$ = 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 $BR(B^0_s \to µ^+µ^−) < 5.6 × 10^{−8}$ and $BR(B^0 \to µ^+µ^−)< 1.5 × 10^{−8}$ at 95% confidence level. |
