The decay asymmetries of the weak radiative Hyperon decays 0 and 00 have been measured with high precision using data of the NA48/1 experiment at CERN. From about 52000 0and 15000 00 decays, we obtain for the decay asymmetries 0 = -0.704 +- 0.019stat +- 0.064syst and 00 = -0.729 +- 0.030stat +- 0.076syst, respectively. These results are in good agreement with previous experiments, but more precise.

Abstract

The decay asymmetries of the weak radiative Hyperon decays 0 and 00 have been measured with high precision using data of the NA48/1 experiment at CERN. From about 52000 0and 15000 00 decays, we obtain for the decay asymmetries 0 = -0.704 +- 0.019stat +- 0.064syst and 00 = -0.729 +- 0.030stat +- 0.076syst, respectively. These results are in good agreement with previous experiments, but more precise.
