Prompt photon hadroproduction at high energies in off-shell gluon-gluon fusion

Understand

The amplitude for production of a single photon associated with quark pair in the fusion of two off-shell gluons is calculated.

• The matrix element found is applied to the inclusive prompt photon hadroproduction at high energies in the framework of kt-factorization QCD approach.
• The total and differential cross sections are calculated in both central and forward pseudo-rapidity regions.
• The conservative error analisys is performed.
