Observation of the rare decay KS→π0μ+μ-
- 1. Cavendish Laboratory, University of Cambridge, Cambridge, CB3 0HE (United Kingdom)
Description
A search for the decay KS→π0μ+μ- has been made by the NA48/1 Collaboration at the CERN SPS accelerator. The data were collected during 2002 with a high-intensity KS 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(KS→π0μ+μ-)=[2.9-1.2+1.5(stat)±0.2(syst)]x10-9
