We use the kT –factorization approach to calculate total and differential cross sections of associated production of prompt photons and hadronic jets at the LHC energies. Our consideration relies on the pegasus Monte-Carlo generator with implemented ℴ (αα 2 s ) off-shell gluon–gluon fusion subprocess g * g * → γqq − and several subleading quark-initiated contributions from ℴ (αα s ) and ℴ (αα 2 s ) subprocesses, taken into account in the collinear limit. Using Monte-Carlo generators CASCADE and PYTHIA, we investigate parton showering effects and compare our predictions with the data, taken by CMS and ATLAS collaborations at the LHC. We demostrate reasonabledescription of the data and the importance of parton shower effects in the kT –factorization.
