Hyperon polarization from the twist-3 distribution in the unpolarized proton-proton collision

Yuji Koike, Kenta Yabe, Shinsuke Yoshida

We investigate the transverse polarization of a hyperon produced in the high-energy unpolarized proton-proton collision, $pp\to {\Lambda }^{\uparrow }X$, based on the collinear twist-3 factori…
