Abstract:
A search for the decay K-S -->pi(o) mu(+) mu(-) has been made by the NA48/1 Collaboration at the CERN SPS accelerator. The data were collected during 2002 with a high-intensity K-S beam. Six events were found with a background expectation of 0.22(-0.11)(+0.18) events. Using a vector matrix element and unit form factor, the measured branching ratio is B(K-S --> pi(o) mu(+) mu(-)) = [2.9(-1.2)(+1.5) (stat) +/- 0.2(syst)] X10(-9).
