Longitudinal polarization of $\Lambda$ and $\bar{\Lambda }$ in deep-inelastic scattering at COMPASS

M. G. Sapozhnikov

Production of $\Lambda$ and $\bar{\Lambda }$ hyperons in deep-inelastic scattering of 160 GeV/c polarized muons is under study in the COMPASS (CERN NA58) experiment. Preliminary results on longit…
