Polarization transfer in hyperon decays and its effect in relativistic nuclear collisions

F. Becattini, Gaoqing Cao, Enrico Speranza

We calculate the contribution to the polarization of $\Lambda$ hyperons in relativistic nuclear collisions at high energy from the decays of ${\Sigma }^{\ast }(1385)$ and ${\Sigma }^0$, which are the predomin…
