Abstract

We use results for the structure functions $F_{L}$ for a gluon target having nonzero transverse momentum square at order $α_{s}$ , obtained in our previous paper, to compare with recent H1 experimental data for $F_{L}$ at fixwd W values and with collinear GRV predictions at LO and NLO approximation.
