Prompt photon production with $k_T-$factorization
  We consider the prompt photon production at modern high energy colliders in the framework of $k_T-$factorization approach. We compare our theoretical predictions with recent experimental data at HERA and Tevatron, empahasizing the distinction between our theoretical predictions and the results of NLO QCD calculations. Finally, we extrapolate our predictions to LHC energies.
