Abstract
From the 2002 data taking with a neutral kaon beam extracted from the CERN-SPS, the NA48/1 experiment observed 97 Ξ0→Σ+μ−ν¯μ candidates with a background contamination of 30.8±4.230.8±4.2 events. From this sample, BR(Ξ0→Σ+μ−ν¯μ) is measured to be (2.17±0.32stat±0.17syst)×10E−6.File in questo prodotto:
