Abstract

A study of the polarization of L hyperons produced in inelastic pN reactions induced by the 450 GeV proton beam from the CERN SPS has been performed with the NA48 detector. The L hyperons were detected at a fixed angle of 4.2 mrad in the momentum range from 50 GeV/c to 200 GeV/c. The polarization changes from -0.053 ±0.034 to -0.298 ±0.074 for a transverse momentum range of the L between 0.28 GeV/c and 0.86 GeV/c. The [`(L)] polarization is consistent with zero.
