GlueX Collaboration Meeting

February 13 to 15, 2020 at Jefferson Lab

The following template has been set up to allow people to identify what needs to be presented at the meeting. It has been roughly broken out by working group with suggestions for topics within each group. The working group chairs should work on adding the relevant talks with an estimated time (including questions) and the speaker's name. If there is a talk that does not fit into this template, please add it at the bottom.


Everyone participating in the collaboration meeting whether in person at JLab or remotely via electronic media are encouraged to register. Please visit the Registration Page.

  • All attendees are also required to register at the following link to enter their visit request. This appears to be different from the meeting registration page.
  • You can also check your currenttraining status to see if you are missing anything that will prevent you getting into the lab.

To see who else will be attending either in person or via electronic media, please see the Current List of Participants Page

Visits to JLab by Foreign Citizens

  • Non-U.S. citizens will be granted lab access for up to one year, or to the end of their U.S. entry authorization, whichever is shorter. Visitors can request annual extensions if their Jefferson Lab host verifies a continuing need for lab access.


All sessions will be in CEBAF Center F113.
