How large is the gluon polarization in the statistical parton distributions approach?

High Energy Physics - Phenomenology 2015-06-23 v1 High Energy Physics - Experiment

Abstract

We review the theoretical foundations of the quantum statistical approach to parton distributions and we show that by using some recent experimental results from Deep Inelastic Scattering, we are able to improve the description of the data by means of a new determination of the parton distributions. We will see that a large gluon polarization emerges, giving a significant contribution to the proton spin.
