Quarkonium+γ production in coherent hadron–hadron interactions at LHC energies

In this paper we study the H + γ ( H = J / Ψ and ϒ ) production in coherent hadron–hadron interactions at LHC energies. Considering the ultrarelativistic protons as a source of photons, we estimate the γ + p → H + γ + X cross section using the non-relativistic QCD (NRQCD) factorization formalism and...

Zusammenfassung:	In this paper we study the H + γ ( H = J / Ψ and ϒ ) production in coherent hadron–hadron interactions at LHC energies. Considering the ultrarelativistic protons as a source of photons, we estimate the γ + p → H + γ + X cross section using the non-relativistic QCD (NRQCD) factorization formalism and considering different sets of values for the matrix elements. Our results for the total p + p → p + H + γ + X cross sections and rapidity distributions at demonstrate that the experimental analysis of the J / Ψ + γ production at LHC is feasible.
