- Title
J/ψ production in hadron scattering: three-pomeron contribution.
- Authors
Levin, E.; Siddikov, M.
- Abstract
In this paper we discuss the inclusive J / ψ production in proton–proton collisions from fusion of three pomerons. We demonstrate that this mechanism gets dominant contribution from the region which can be theoretically described by CGC/saturation approach. Numerically, it gives a substantial contribution to the J / ψ production, and is able to describe the experimentally observable shapes of the rapidity, momenta and multiplicity distributions. The latter fact provides a natural explanation of the experimentally observed enhancement of multiplicity distribution in J / ψ production.
