Abstract: The surprising polarization of $\mathrm{\ensuremath{\Lambda}}$'s and other hyperons measured in many unpolarized hadronic processes, $pN\ensuremath{\rightarrow}{\mathrm{\ensuremath{\Lambda}}}^{\ensuremath{\uparrow}}X$, has been a long-standing challenge for QCD phenomenology. One possible explanation was suggested, related to nonperturbative properties of the quark… read more here.

DOI: 10.1103/physrevd.102.054001
Abstract: We present a thorough phenomenological analysis of the experimental data from Belle Collaboration for the transverse $\Lambda$ and $\bar\Lambda$ polarisation, measured in $e^+e^-$ annihilation processes, for the case of inclusive (plus a jet) and associated… read more here.
