Abstract

An NLO photon parton parametrization is presented based on the existing measurements from e ⁺ e ^- data and the low-x proton structure function from ep interactions. Also included in the extraction of the NLO parton distribution functions are the dijets data coming from γp → j ₁ + j ₂ + X. The new parametrization is compared to other NLO parametrizations.
