Summary
The quarkonium plus photon production in coherent hadron - hadron interactions at LHC is studied using the non-relativistic QCD (NRQCD) factorization formalism. Considering two different sets of NRQCD matrix elements we estimate the rapidity distribution and total cross sections for $J/\Psi + \gamma$ and $\Upsilon + \gamma$ production. Our results demonstrate that the experimental analysis of this process is feasible and that it can be used to constrain the matrix elements.
