Abstract

The recent LHCb data for exclusive J y 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 factorisation approaches.
