Asymptotic Safety meets Particle Physics & Friends

15 Dec 2021, 13:00 → 17 Dec 2021, 17:00 Europe/Zurich

This workshop brings together researchers interested in the subject of asymptotic safety, renormalization group and particle physics to discuss the theory, phenomenology and recent advances in the field, to explore future avenues and compare findings with experiment. This is the 8th event of this kind.

 

This is a hybrid event, held both remotely via Zoom as well as in-person at TU Dortmund. Please note that space is limited and Covid restrictions apply for the latter.
