DESCRIPTION:Speakers: Maxim Nefedov (Samara State University)\nWe study th
 e photoproduction of isolated prompt photons associated with jets in the f
 ramework\nof the parton Reggeization approach. The data on pseudorapidity 
 and transverse momentum\ndistributions of the photon and jet\, obtained by
  H1 and ZEUS Collaborations at DESY HERA\,\nare described with the good ac
 curacy\, as well\, as the data on azimuthal decorrelation variables.\nThe 
 main improvements of the present calculation\, with respect to the previou
 s studies in the kT -\nfactorization framework\, are the usage of Reggeize
 d quarks formalism\, to provide exactly gauge-\ninvariant amplitudes with 
 off-shell initial state quarks\, and the first exact treatment of the γR 
 → γg\nbox contribution with off-shell initial state gluons.\n\nhttps://
