Abstract

New data, especially HERA measurements of the proton structure function at small x, allow the opportunity to improve our knowledge of the gluon and quark distribution functions. We perform a global analysis which incorporates these new precise data, and which extends down to Q 2 = 1.5 GeV 2. We discuss the sensitivity to the value of α s and the improvement in the determination of the gluon. We compare the predictions of the single jet inclusive cross section with recent measurements from the Fermilab Tevatron.
