Description
We study the photoproduction of isolated prompt photons associated with jets in the framework
of the parton Reggeization approach. The data on pseudorapidity and transverse momentum
distributions of the photon and jet, obtained by H1 and ZEUS Collaborations at DESY HERA,
are described with the good accuracy, as well, as the data on azimuthal decorrelation variables.
The main improvements of the present calculation, with respect to the previous studies in the kT -
factorization framework, are the usage of Reggeized quarks formalism, to provide exactly gauge-
invariant amplitudes with off-shell initial state quarks, and the first exact treatment of the γR → γg
box contribution with off-shell initial state gluons.
