Title: Near threshold J / ψ and ϒ photoproduction at JLab and RHIC

Abstract

We update our previous calculation of J/ψ photo-production near threshold by incorporating the recent developments in theory and the new experimental data from the GlueX collaboration at Jefferson Lab. We then propose to study the near threshold production of Υ and J/ψ in ultraperipheral pA collisions at RHIC. These processes are sensitive to the gluon condensate in the proton which is related to the QCD trace anomaly. Our result emphasizes the role of gluons as the origin of the proton mass.

FIG. 1 FIG. 1: Left panel : Fits of the GlueX data for the total cross section. The red curve corresponds to b = 0 and the blue curve corresponds to b = 1. Right panel : Comparisons between the GlueX data and our model for differential cross sections, where $δt$ =more » $t$−$t$min. Color assignments are the same as the left panel, while the solid, dashed, and dot-dashed curves correspond to $E$$γ$ = 10, 10.3, and 10.6 GeV, respectively. The experimental data are taken for 10 < $E$$γ$ < 11.8 GeV.« less
