Dear all,

Next RESCEU Monday seminar is on Nov. 22, 15:30-16:30.
The seminar is the continuation of the last seminar, and the information is as follows.

Title:Two-group symmetry in QED

Speaker:Fumio Uchida

Abstract:
Symmetry is one of the most fundamental concepts in physics. However, well-known symmetries as of the Standard Model belong to just the simplest class of its generalizations [1-3]. In the talk, we will see two-group symmetry in massless and multi-flavor QED, as an explicit example of the wider symmetry class. I hope the talk will be complementary to the forthcoming lecture [4].
