Abstract

The decay rate of K_S → π e ν relative to the rate of K_L → π e ν has been measured by the NA48 Collaboration in a neutral kaon beam originating from 400 GeV proton-Be interactions at the CERN SPS. The result is 0.993 ± 0.026_stat ± 0.022_syst, compatible with 1 in agreement with the Standard Model prediction at tree level. It implies B R (K_S → π e ν) = (7.05 ± 0.18_stat ± 0.16_syst) × 10^-4.
