Abstract:
A search for the decay $ K_{\mathrm{S}}^0\to {\mu^{+}}{\mu^{-}} $ is performed, based on a data sample of 1.0 fb −1 of pp collisions at $ \sqrt{s}=7\;\mathrm{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 $ \mathcal{B}\left( {K_{\mathrm{S}}^0\to {\mu^{+}}{\mu^{-}}} \right) $ 〈 11(9) × 10 −9 at 95 (90)% confidence level. This limit is a factor of thirty below the previous measurement.
