First evidence for the rare decay $B^0_S\rightarrow\mu^+\mu^-$
LHCb observed evidence for a very rare decay of a neutral $B_S$ meson into a pair of muons[1]. The probability that the background could produce such an excess or larger is mere 5.3 x $10^{-4}$. This corresponds to signal significance of 3.5 standard deviations in the combined 1.0fb$^{-1}$ of 2011 (...

description | LHCb observed evidence for a very rare decay of a neutral $B_S$ meson into a pair of muons[1]. The probability that the background could produce such an excess or larger is mere 5.3 x $10^{-4}$. This corresponds to signal significance of 3.5 standard deviations in the combined 1.0fb$^{-1}$ of 2011 (√s=7TeV) and 1.11f$^{-1}$ of 2012 (√s=8TeV) data. |
