Abstract
To obtain improved parton densities of the proton, we present a new global analysis of deep inelastic and related data including, in particular, the recent measurements of at HERA, of the asymmetry of the rapidity distributions of production at the FNAL collider and of the asymmetry in Drell-Yan production in and collisions. We also incorporate data to determine the flavour dependence of the quark sea distributions. We find that the behaviour of the partons at small is consistent with the precocious onset of BFKL leading dynamics. We discuss the ambiguities remaining in the gluon distribution. We present improved predictions for boson (and quark) production at the FNAL collider.
