Energy dependence of dissociative J/Psi photoproduction as a signature of gluon saturation at the LHC

Popis výsledku v původním jazyce

We have developed a model in which the quantum fluctuations of the proton structure are characterised by hot spots, whose number grows with decreasing Bjorken-x. Our model reproduces the F-2(x, Q(2)) data from HERA at the relevant scale, as well as the exclusive and dissociative J/Psi photoproduction data from H1 and ALICE. Our model predicts that forW(gamma p)approximate to 500GeV, the dissociative J/Psi cross section reaches a maximum and then decreases steeply with energy, which is in qualitatively good agreement to a recent observation that the dissociative J/Psi background in the exclusive J/Psi sample measured in photoproduction by ALICE decreases as energy increases. Our prediction provides a clear signature for gluon saturation at LHC energies. (C) 2017 The Authors. Published by Elsevier B.V.
