Reanalyzing two inclusive&Lgr;0polarization data samples, created fromproton-nucleuscollisions, we found that&Lgr;0polarization is well described, in the average, byP(xF,PT)=(−0.450±0.018)xFPT+(0.060±0.007),with−1<xF<PT GeV/c.This function fits also&Lgr;¯0polarization created inpp¯→&Lgr;¯0Xreactions, and&Ygr;−polarization. ©1999 American Institute of Physics.
