Gluons from logarithmic slopes of $F_{2}$ in the NLL approximation

High Energy Physics - Phenomenology 2009-09-25 v1

Abstract

We make a critical, next-to-leading order, study of the accuracy of the Prytz relation, which is frequently used to extract the gluon distribution at small xx from the logarithmic slopes of the structure function F2F_{2}. We find that the simple relation is not generally valid in the Hera regime, but show that it is a reasonable approximation for gluons which are sufficiently singular at small xx.
