The description of F$_{2}$ at small x incorporating angular ordering

We study the perturbative QCD description of the HERA measurements of F_2 (x, Q^2) 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 F_2. We present estimates of the charm component F_2^c (x, Q^2) and of F_L (x, Q^2)
