Exclusive J/psi and Upsilon photoproduction and the low x gluon
Abstract
We discuss the potential to constrain the small-x PDFs using the exclusive production of heavy vector mesons. The calculation of J/ and photoproduction at NLO in collinear factorisation is described. The different behaviour of the NLO corrections for J/ and is highlighted and we outline what might be expected from the inclusion of these processes in a PDF fit.
