Abstract

The production of Lambda and Lambda-bar hyperons by polarized muons of 160 GeV/c on a polarized 6LiD target has been studied using the COMPASS spectrometer. First preliminary results on the longitudinal polarization of Lambda and Lambda-bar hyperons produced in the deep-inelastic scattering will be presented for 2002 data set.
