QCD relations between structure functions at small x

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

We present very simple non-integral relations between deep inelastic structure functions FLF_L, F2F_2 and the gluon distribution at small xx based on perturbative QCD which are useful for the phenomenological analysis of data at low xx. As an application we extract the deep inelastic scattering cross-sections ratio R=σL/σTR= \sigma_L/\sigma_T in the range 104x10210^{-4} \leq x \leq 10^{-2} from F2F_2 HERA data.
