Production of γγ+ 2jets from double parton scattering in proton-proton collisions at the LHC

الأصل · EN

Cross sections for the production of pairs of photons plus two additional jets produced from double parton scattering in high-energy proton-proton collisions at the LHC are calculated for the first time. The estimates are based on the theoretical perturbative QCD predictions for the productions of γγat next-to-next-to-leading-order, jet + jet and γ+ jet at next-to-leading-order, for their corresponding single-scattering cross sections. The cross sections and expected event rates for γγ+ 2 jets from double parton scattering, after typical acceptance and selections, are given for proton-proton collisions with the center-of-mass energies of 13 TeV and an integrated luminosity of 100 fb-1 planned for the following two years, and also center-of-mass energies of 14 TeV with 3000 fb-1 of integrated luminosity as LHC designed.
