The Gluon Distribution as a Function of F2 and dF2/dlnQ2 at small x. The Next-to-Leading Analysis
Abstract
We present a set of formulae to extract the gluon distribution function from the deep inelastic structure function F2 and its derivative dF2/dlnQ2 at small x in the leading and next-to-leading order of perturbation theory. The detailed analysis is given for new HERA data. The values of the gluon distribution are found in the range 10-4 ≤ x ≤ 10-2 at Q2=20 GeV2.
