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