摘要
In the framework of the k(t)-factorization approach, the photon-associated production of Upsilon mesons at the present-day LHC conditions is studied. The differential cross sections and polarization parameters are calculated in the "helicity" and Collins-Soper systems. Special attention is paid to the effect of experimental cuts that can dramatically change the visible lepton angular distributions.
