*********************************
(1) (Jo Dudek) TOPIC 1: Production Mechanisms. While the GlueX Experiment uses 9 GeV polarized photons incident on a proton target to produce hadrons (photoproduction), the BESIIII Experiment collides electrons and positrons to produce hadrons through a virtual photon (e+e- annihilation). Can these two processes, one through a real photon and one through a virtual photon, be related in a rigorous way? Can we take information learned from e+e- and make predictions about photoproduction cross sections? Is there anything interesting to learn about spectroscopy by doing this?

(1b) (Jo Dudek) Lattice QCD calculations of electron-positron and photoproduction couplings (Thy)
**********************************
Thursday, August 17, 14:00 - 17:00
**********************************
(2) (Chengping Shen) TOPIC 2: Light and Heavy Quark Hadrons. Can we use what has been observed by BESIII in the charmonium system to make definitive, testable predictions for GlueX? How could the scientific program at GlueX benefit from the ongoing developments in charmonium? Could key ideas stemming from charmonium (cusps, rescattering, tetraquarks, etc.) be tested at GlueX?
(2a) (Zhu Kai) Experimental summary of the XYZ states at BESIII (Exp)
(2b) (Jun He) Hadronic molecules and their production in e+e- annihilation and photoproduction (Thy)
(2c) (Adam Szczepaniak) If the XYZ are tetraquarks, hybrids, cusps, etc. what should we see in the light quark sector? (Thy)
*******************************
Friday, August 18, 9:00 - 12:00
*******************************
(3) (Justin Stevens) TOPIC 3: Light Quark Resonances. How can we use knowledge of light quark mesons and baryons obtained from charmonium decay to inform analyses for GlueX? Are there interesting light quark structures observed at BESIII that should be high priority searches at GlueX? What might we learn if GlueX does or does not observe them?
(3a) (Beijiang Liu) Overview of light quark resonances at BESIII (Exp)
(3b) (Qiang Zhao) Disentangling hadron properties using e+e- annihilations and photoproduction reactions (Thy)

********************************
(4) (Haiping Peng) TOPIC 4: Theory-Experiment Collaboration. How can theorists interact with BESIII and GlueX to maximize the amount that can be learned from data? How can the experiments facilitate these interactions?
(4a) (Vincent Mathieu) Overview of the JLab Physics Analysis Center (JPAC) (Thy)
(4b) (Wolfgang Gradl) What should experimentalists publish? (Exp/Thy)
(4c) (Changzheng Yuan) Concerns from experimentalists about theory collaboration (Exp)
