The description of F2 at small x incorporating angular ordering
J. Kwiecinski, A. D. Martin, P. J. Sutton
Abstract
We study the perturbative QCD description of the HERA measurements of F2 (x, Q2) using a gluon distribution that is obtained from an evolution incorporating angular ordering of the gluon emissions, and which embodies both GLAP and BFKL dynamics. We compare the predictions with recent HERA data for F2. We present estimates of the charm component F2c (x, Q2) and of FL (x, Q2).
