Longitudinal Spin Transfer to $\Lambda$ and $\bar{\Lambda }$ Hyperons in Polarized Proton-Proton Collisions at $\sqrt{s}$ = 200 GeV

The STAR Collaboration, B. I. Abelev

The longitudinal spin transfer, $D_{LL}$, from high energy polarized protons to $\Lambda$ and $\bar{\Lambda }$ hyperons has been measured for the first time in proton-proton collisions at $\sqrt{…
