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.8 pages, 7 figures, submitted to the Proceedings of XI Workshop on High Energy Spin Physics "SPIN-05", Dubna, September 2005High Energy Physics - Experimenttext
