Abstract

A total of 368 415 Ξ0→Λπ0 and 31 171 were selected from data recorded in the NA48/1 experiment during 2002 data taking. From this sample, the polarization of Ξ0 and hyperons was measured to be PΞ0=−0.102±0.012(stat)±0.008(syst) and PΞ0bar=−0.01±0.04(stat)±0.008(syst). The dependence of PΞ0 on the Ξ0 transverse momentum with respect to the primary proton beam is also presented. With the same data sample, the ratio of and Ξ0 fluxes in proton collisions at 400 GeV/c on a beryllium target was measured.
