文摘

In this paper we give estimates for the proton–proton cross sections into pairs of quarkonium states J/ψJ/ψ, ψ(2S)ψ(2S), ϒ(1S)ϒ(1S) and ϒ(2S)ϒ(2S) at the scheduled AFTER@LHC energy of 115 GeV. The estimates are based on the intrinsic heavy quark mechanism which is observable for high values of xFxF, a range outside the dominance of single parton and double parton scattering.
