Abstract

A search for the decay K 0 S →μ + μ − is performed, based on a data sample of 1.0 fb−1 of pp collisions at s √ =7TeV 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 B(K 0 S →μ + μ − ) < 11(9) × 10−9 at 95 (90)% confidence level. This limit is a factor of thirty below the previous measurement.
