QCD resummation effects in forward $J/ψ$ and very backward jet inclusive production at the LHC

Abstract

We propose and study the inclusive production of a forward $J/ψ$ and a very backward jet at the LHC as an observable to reveal high-energy resummation effects à la BFKL. Our different predictions are based on the various existing mechanisms to describe the production of the $J/ψ$, namely, NRQCD singlet and octet contributions, and the color evaporation model.
