<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;">Dear Colleagues,<br><br>In place of the Theory Seminar on Monday, April 24th we will have an informal meeting about the <br>physics of ultraperipheral collisions at LHC/RHIC and its connections to the EIC (summary talks <br>+ extensive discussion). Please see announcement below. All JLab Theory Center members are <br>encouraged to attend.<br><br><br><br>--------------------<br><br><br><b>High-energy electromagnetic processes in ultraperipheral collisions at LHC/RHIC and the EIC</b><br><br><br>Time: Monday, April 24th, 1pm-3pm+ EDT<br>Location: JLab CC L102, remote participation through BlueJeans<br><br><br>Ultraperipheral nucleus-nucleus and proton-nucleus collisions at LHC and RHIC allow one to study<br>high-energy photoproduction processes at CM energies W ~ 500-1800 GeV, using the heavy nucleus as<br>a source of Weizsaecker-Williams photons. The physics explored in these electromagnetic processes<br>has many connections with the scientific program of a future Electron-Ion Collider (nuclear shadowing,<br>non-linear effects, gluon saturation, nucleon imaging). The informal meeting is intended to give an<br>overview of the present status and future prospects of ultraperipheral collisions (UPCs), their<br>theoretical interpretation, and the connections with the EIC physics program.<br><br><br>Agenda:<br>1:00pm-1:10pm C.
