Predictions based on leading-logarithm parton-shower Monte Carlo models and next-to-leading-order (NLO) QCD underestimate the gamma+jet cross sections for transverse energies of prompt photons below 7 GeV, while the kT-factorisation QCD calculation agrees with the data in this region.Proceedings of the XV International Workshop on Deep Inelastic Scattering (DIS07 April 16-20, 2007, Munich, Germany)High Energy Physics - Experimenttext
