Quarkonium +γ production in coherent interactions at LHC

摘要

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