Associated production of $J/\ddot{I}ˆ$ and direct photon in the NRQCD and the ICEM using the high-energy factorization

Lev Alimov, Anton Karpishkov, Vladimir Saleev

We study the associated $J/\ddot{I}ˆ$ and direct photon production in the high-energy factorization, as it is formulated in the parton Reggeization approach, using two different models fo…
