Abstract
The longitudinal polarization of Lambda and anti-Lambda hyperons produced in deep-inelastic scattering of 160 GeV/c polarized muons is studied in the COMPASS experiment. Preliminary results on x- and y- dependence of the longitudinal polarization of Lambda and anti-Lambda from data collected during the 2003 run are presented.
