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 γγ at 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 collision energy and integrated luminosity of 100 fb−1 planned for the following years, and also with 3000 fb−1 of integrated luminosity as the LHC design. |
