NLO photon parton parametrization

arXiv:hep-ph/0507091 · doi:10.1063/1.2122150

Abstract

An NLO photon parton parametrization is presented based on the existing $F_{2}^{3}$ measurements from $e^{+} e^{-}$ data and the low- $x$ proton structure function from $e p$ interactions. Also included in the extraction of the NLO parton distribution functions are the dijets data coming from $I^^{3} p \to j_{1} + j_{2} + X$ . The new parametrization is compared to other available NLO parametrizations.
