Probing the Photon Structure Function in Photoproduction

Abstract

We show how the parton distributions in the photon can be accurately measured in the photoproduction of large-pt jets at HERA. A short review is given of the beyond Leading Logarithm formalism for the photon structure function, with a discussion of the factorization scheme and of the non-perturbative input.
