NLO Monte-Carlo approach in 1 or 2 jets Photoproduction
  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.
