Abstract:
A study of the polarization of Lambda hyperons produced in inelastic pN reactions induced by the 450 CeV proton beam from the CERN SPS has been performed with the NA48 detector. The Lambda 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 Lambda between 0.28 GeV/c and 0.86 GeV/c. The <(Lambda)over bar> polarization is consistent with zero.
