Description

Kaon decays are a new area of interest at the LHCb experiment. A search for the decay K0S -> mu+ mu- is performed, based on a data sample of 1.0 fb^-1 of pp collisions at sqrt(s) = 7 TeV. The observed number of candidates is consistent with the background-only hypothesis, yielding an upper limit of B(K0S -> mu+ mu-) < 11 (9) x 10^-9 at 95 (90)% confidence level. This limit is a factor of thirty below the previous measurement. Prospects for this and other decays of strange particles are also presented.
