to the CEBAF accelerator</span><span style="font-size:12pt; color:black; font-family:Calibri,Helvetica,sans-serif">. The workshop</span><span style="font-size:14.0pt; color:black"><span style="background:white; font-family:Calibri,Helvetica,sans-serif; font-size:12pt">
will take place at the laboratory from Monday, January 23, to Wednesday, January 25, 2023. This workshop will encompass the broad spectrum of topics in medium energy physics enabled by the potential upgrade, and will feature theoretical advances as well as
recent and potential results. Concrete projections for experiments are encouraged. Topics will include:</span></span><span style="font-size:12.0pt; color:black"></span></p>
