Dihadron Azimuthal Correlation from Collins Effect in Unpolarized Hadron Collisions

High Energy Physics - Phenomenology 2014-11-20 v1

Abstract

We study the dihadron azimuthal correlation produced nearly back-to-back in unpolarized hadron collisions, arising from the product of two Collins fragmentation functions. Using the latest Collins fragmentation functions extracted from the global analysis of available experimental data, we make predictions for the azimuthal correlation of two-pion production in pppp collisions at RHIC energies. We find that the correlation is sizable in the mid-rapidity region for moderate jet transverse momentum.
