On the role of Collins effect in the single spin asymmetry A_N in p(transv. polarized) p --> h X processes

M. Anselmino, M. Boglione, U. D'Alesio +4

The much debated issue of the transverse single spin asymmetry A_N observed in the inclusive large P_T production of a single hadron in pp interactions, p(transv. polarized) p -->…
