California Amplitudes Meeting 2022

California Amplitudes Meeting

QMAP, UC Davis, March 5-6, 2022

The meeting will be held in the space of the Center for Quantum Mathematics and Physics (QMAP). The focus is on various topic in scattering amplitudes and recent developments. It is mainly aimed at researchers located in California.

Covid procedure:

Masks indoors required, you need to fill the Daily Symptom Survey every day you enter UC Davis facilities: Unvaccinated participants must also wear masks outdoors. 


All talks will be in the QMAP seminar room (3rd floor). Lunches and coffee breaks will be in the kitchen area on the 2nd floor. Saturday afternoon is devoted to discussions, we will then go for dinner at 6:00pm in downton Davis (in multiple groups). 


The workshop starts on Saturday, March 5, 9:30am and ends on Sunday, March 6, 2:00pm.
