Abstract

The decay asymmetries of the weak radiative hyperon decays Xi(0) -> Lambda gamma and Xi(0) -> Sigma(0)gamma have been measured with high precision using data of the NA48/1 experiment at CERN. From about 52 000 Xi(0) -> Lambda gamma and 15 000 Xi(0) -> Sigma(0)gamma decays, we obtain for the decay asymmetries alpha(Xi 0 -> Lambda gamma) = -0.704 +/- 0.019(stat) +/- 0.064(syst) and alpha(Xi 0 -> Sigma 0 gamma) = -0.729 +/- 0.030(stat) +/- 0.076(syst), respectively. These results are in good agreement with previous experiments, but more precise. (C) 2010 Elsevier B.V. All rights reserved.
