Search for the rare $K^0_s \to \mu^+ \mu^-$ decay
A search for the decay $K^0_s \to \mu^+ \mu^-$ is performed, based on a data sample of 1.0 fb$^{-1}$ of pp collisions at $\sqrt{s}$ = 7 TeV collected by the LHCb experiment at the Large Hadron Collider. The observed number of candidates is consistent with the background-only hypothesis, yielding a...

| description | A search for the decay $K^0_s \to \mu^+ \mu^-$ is performed, based on a data sample of 1.0 fb$^{-1}$ of pp collisions at $\sqrt{s}$ = 7 TeV collected by the LHCb experiment at the Large Hadron Collider. The observed number of candidates is consistent with the background-only hypothesis, yielding an upper limit of ${\cal B}(K^0_s \to \mu^+ \mu^-) < 11(9) \times 10^{-9}$ at 95 (90)% confidence level. This limit is a factor of thirty below the previous measurement. |
