Measurements of the $\Xi^0$ lifetime and the $\overline{\Xi^0}/\Xi^0$ flux ratio in a neutral beam

A total of 235 698 Xi0 -> Lambda pi0 and 21 527 anti-Xi0 -> anti-Lambda pi0 decays were selected from data obtained by the NA48/1 experiment at CERN. From this sample, the lifetime of the Xi0 hyperon was measured to be (3.065 +- 0.012(stat) +- 0.014(syst)) x 10^-10 s. This result is about two...
