The Gluon Distribution as a Function of F 2 and dF 2 /dlnQ 2 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 F
2
and its derivative dF
2
/dlnQ
2
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
