This is an informal seminar where students, postdocs and faculty discuss research progress as well as plans for future research. Starting from Fall 2023, we conduct the seminar together with our friends from high energy theory. The schedule can be found here.
Location: Galallee Hall, Room 328.
Time: Thursday, 5:00 p.m.
Contact: Georg Schwiete
