Collins function for pion-in-jet production in polarized $pp$ collisions: a test of universality and factorization

Umberto D'Alesio, Carlo Flore, Marco Zaccheddu

We present an updated study of the Collins azimuthal asymmetries for pion-in-jet production in polarized $pp$ collisions. To this aim, we employ a recent extraction of the transver…

First extraction of the $Λ$ polarising fragmentation function from Belle $e^{+} e^{-}$ data

Umberto D'Alesio, Francesco Murgia, Marco Zaccheddu

We present a thorough phenomenological analysis of the experimental data from Belle Collaboration for the transverse $Λ$ and $Λ ˉ$ polarisation, measured in $e^{+} e^{-}$ annihilation…

Transverse single spin asymmetries in Drell-Yan processes

M. Anselmino, U. D'Alesio, F. Murgia

Recently, it has been shown, contrary to previous beliefs, that the k_T distribution of quarks in a transversely polarized proton can be asymmetric. This ``Sivers effect'' had alre…
