Abstract

A new precision measurement of the Xi^0 mass has been performed at the NA48 experiment at the CERN SPS. The value obtained is [1314.82 +- 0.06 (stat.) +- 0.2 (syst.)] MeV/c^2. The branching ratios of Xi^0 radiative decays have been measured as: Br(Xi^0 --> Lambda gamma) = [1.90 +- 0.34 (stat.) +- 0.19 (syst.)] * 10^-3 and Br(Xi^0 --> Sigma^0 gamma) = [3.14 +- 0.76 (stat.) +- 0.32 (syst.)] * 10^-3.
