Abstract
We present a method for calculating the photoproduction of jets at HERA based on
Next to Leading Logarithm QCD calculations. It is implemented in a Monte-Carlo generator which
allows us to easily compute any infra-red safe cross sections for 1 or 2 jet observables using
various jet reconstruction algorithms. We focus on the possibility of extracting the gluon
contents of the photon and of the proton from present and future H1 and ZEUS
data.
