Exclusive J/ production at the LHC in the kT factorization approach
Abstract
The recent LHCb data for exclusive J/ peripheral production at 13 TeV motivate an improved `NLO' analysis to estimate the gluon distribution at low x in which we re-calculate the rapidity gap survival factors and use a more precise expression for the photon flux. We comment on the difference between the kT and collinear factorization approaches.
