Abstract

We have measured the polarization ofSigma + and bar Sigma hyperons at 375 GeV/c produced by 800 GeV/c protons on a copper target atpT up to 17 GeV/c The polarization behaviour is compared and contrasted with that of other hyperons and antihyperons in similar kinematic regionsFermilab Carnegie Mellon SUNY at Albany University of Iowa Yale USA Universidade Federal de Paraiba CBPF CNPq Rio de Janeiro Universidade de São Paulo Brazil IHEP Beijing PRC PNPI Gatchina ITEP Moscow Russia University of Bristol UK
