Prompt photon hadroproduction in the k_T-factorization approach
  We study the production of prompt photons at high energy in the framework of the k_T-factorization approach. The amplitude for production of a single photon associated with quark pair in the fusion of two off-shell gluons is calculated.   Theoretical results are compared with the Tevatron data.
