Description
In this talk we present the analysis of prompt photon production at the LHC with the kT-factorization approach. We consider two leading partonic channels, qg->q\gamma and gg*->q\bar{q}\gamma and three theoretical schemes known under the acronyms KMR, GBW, CCFM. We find sensitivity of the calculated prompt photon transverse momentum distribution to the gluon transverse momentum distribution. The predictions are compared to precise data from ATLAS and CMS experiments, what allows to differentiate between approaches.
