QCD Predictions for $g_1^p$ at Small $x$ Incorporating Double $ln^2(1/x)$ Resummation

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/47687The proton spin dependent structure function $g_1^p$ is analysed using the unified scheme incorporating both Altarelli-Parisi evolution and the double $ln^2(1/x)$ effects at low $x$. The latter are found to be very important in the region of $x$ which can possibly be probed at HERA. Predictions for the polarized gluon distribution $ΔG(x)$ at low $x$ are also given.To appear in the Proceedings of the 1997 Workshop on 'Physics with Polarized Protons atHERA', eds.
