$F_2/xG(x,Q^2)$ Ratio at Small $x$ and the Role of the Contribution from Infrared Region

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/148105We consider the light quark electroproduction cross section and show that the contribution coming from the infrared ($q_T<300\, MeV$) region is not negligible. It changes the $F_2(x,Q^2)/xG(x,Q^2)$ ratio by 20-30\% (or even more) for small $x$ and $Q^2\sim 4\, GeV^2$.12 pages (LaTeX) + 8 uuencoded-compressed-tar postcript figures in a separate fileHigh Energy Physics - Phenomenology$F_2/xG(x,Q^2)$ Ratio at Small $x$ and the Role of the Contribution from Infrared Regiontext
