Abstract

In the recent years many new measurements of the decay of the neutral Xi0 hyperon have been reported both by the NA48/1 and the KTeV collaboration. The results are based on data samples of more than 2 billion Xi0 decays. In this report new measurements of the Xi0 lifetime, decay asymmetries, and semileptonic decay rates are presented. The latter allow the extraction of the CKM matrix element |V_us|, complementary to kaon decays.
