Figure 9. Prediction for proton structure function F2. Data is taken from HERA (H1 [28] and ZEUS [29]) as well as fixed target experiment (NMC [30] and BCDMS [31]). The background contribution is given by (33) with ${F}_{2}^{{BG}}({x}_{0}=0.1)\approx $ 0.316, 0.384, 0.391 and 0.406 corresponding to four Q2 values, namely $5\ {\mathrm{GeV}}^{2},15\ {\mathrm{GeV}}^{2},35\ {\mathrm{GeV}}^{2}$ and $45\ {\mathrm{GeV}}^{2}$.
