Structure Functions and Small X Physics

Abstract

We review recent developments in the determination of parton densities from deep inelastic and related data. We show how the asymmetries observed in the W+- rapidity distributions and in pp/pn Drell-Yan production further constrain the partons at moderate x. We compare the GLAP and BFKL descriptions of the recent measurements of F2(x,Q**2) at HERA. We survey processes which may be used to identify BFKL dynamics.
