Exclusive $J/ψ$ and $Υ$ production in high energy $pp$ and $p$Pb collisions

“…Our predictions agree favourably with the ALICE data, particularly at backward, central [32,33,34]. We emphasise that no fit is made to the data shown, the width of the uncertainty bands is obtained by the ±1σ statistical uncertainties and the normalisation errors of the datasets used in our previous fit [35] to determine the low x gluon PDF, which is used in the present analysis.…”

“…In this section, we compare our theoretical predictions with the rapidity differential cross section data from ALICE [32,33] and CMS [34] for the process p+Pb → p+V +Pb, where V = J/ψ, Υ. Using eqn.…”

“…The smaller value of B 0 for the case V = Υ is due to the need for reducing the J/ψ slope parameter by the factor 4α ln M Υ /M J/ψ . In the right panels, we show our results compared with existing data from ALICE and/or CMS [32,33,34]. The error bands are indicative of the uncertainty due to our previous low x gluon PDF fit [35] only and does not account for theoretical uncertainties in the present formalism.…”

“…Panels (a) and (c) show the decomposition of the total cross section into the σ Pb and σ p contributions, see text for details. Panels (b) and (d) compare our predictions with existing data from ALICE and/or CMS[32,33,34]. We emphasise that no fit is made to the data shown, the width of the uncertainty bands is obtained by the ±1σ statistical uncertainties and the normalisation errors of the datasets used in our previous fit[35] to determine the low x gluon PDF, which is used in the present analysis.…”
