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.
