The heavy charmonium interacts with the light quarks of the proton (that near threshold carry significant fraction of the proton momentum) predominantly via hard gluon exchange. The purpose of the presentation will be to discuss the possibilities of using
the measured cross-sections to study the gluonic distributions in the proton at high x. </span><span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0); background-color: rgb(255, 255, 255); display: inline !important;">The
GlueX detector will be described briefly and the main experimental results will be presented. Theoretical works that describe the J/psi cross-section and relate it to the gluonic distributions will be discussed. </span><span style="font-family: Calibri, Arial, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0); background-color: rgb(255, 255, 255); display: inline !important;">The
production of the LHCb pentaquarks, predicted for the s-channel of the reaction, will not be part of this talk.</span></div>
