Description

Exclusive J/psi production, gamma p->J/psi p, offers a unique opportunity to determine the gluon density of the proton in the small Bjorken x domain. We use the available HERA data to determine the gluon distribution in the region 10^{-4} < x < 10^{-2} for scales 2 < Q^2 < 10 GeV^2, where the uncertainty on the gluon extracted from the global parton analyses is large. We present results for gluons extracted using a LO analysis and for gluons extracted including NLO corrections and compare to the global analyses.
