Alternative methods to measure global polarization of $\Lambda$ hyperons

Abstract

We propose alternative methods to measure the global polarization of $\Lambda$ hyperons. These methods involve event averages of proton's and $\Lambda$'s momenta in the lab frame. We carry out simulations using these methods and show that all of them work equivalently well in obtaining the global polarization of $\Lambda$ hyperons.
