Description
Inclusive heavy vector meson hadroproduction is a subject of vivid experimental studies at the Large Hadron Collider. We consider in detail a new color singlet contribution to the J/psi production at the LHC, that is driven by a double BFKL pomeron exchange between the produced meson and a target parton. This production mechanism is closely related to a small x evolution of double gluon density including parton correlations. We estimate the differential cross sections and discuss their properties and relevance.
