High Energy Theory Informal Meeting 2020-2021

This meeting is for relatively informal discussions on topics that happen to be interesting us - occasionally we also have a formal seminar. The organizer of this seminar is Po-Shen Hsin (phsin@caltech.edu). All talks are via Zoom. (contact the organizer for the zoom link if not on the mail list). The talks are at 1:30pm Pacific time (unless indicated*)
