Semiexclusive production of J/ψ mesons in proton–proton collisions with electromagnetic and diffractive dissociation of one of the protons

Semiexclusive production of J/ψ mesons in proton–proton collisions with electromagnetic and diffractive dissociation of one of the protons

We calculate the cross sections for both electromagnetic and diffractive dissociation of protons for the semiexclusive production of J/ψ mesons in proton–proton collisions at the LHC. Several differential distributions in missing mass (MX), or single-particle variables related exclusively to the J/ψ...
