[Theory-seminars] Cake Seminar tomorrow [1pm, L102]

[Miguel Albaladejo]

Dear all,

below you can find a reminder on tomorrow's cake seminar.

Regards,
Carlota, Raza,Miguel

Wednesday Oct 2, 1:00PM, Room L102
Lubomir Pentchev (JLab), "Probing proton gluonic structure with J/psi exclusive photoproduction''

Abstract:
Recently GlueX published first measurements of near-threshold J/psi exclusive photoproduction. 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. 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. The production of the LHCb pentaquarks, predicted for the s-channel of the reaction, will not be part of this talk.
