Small-x asymptotics of the gluon helicity distribution

Small-x asymptotics of the gluon helicity distribution

Abstract We determine the small-x asymptotics of the gluon helicity distribution in a proton at leading order in perturbative QCD at large N c . To achieve this, we begin by evaluating the dipole gluon helicity TMD at small x. In the process we obtain an interesting new result: in contrast to the un...
