Generalized symmetries for particle physics - Nathaniel Craig (UCSB)

Abstract: The study of generalized symmetries has led to new insights across high energy, condensed matter, and mathematical physics, but the extent of their implications for particle physics remains unclear. In this talk, I’ll explore the extent to which emergent or approximate generalized symmetries might shed new light on familiar phenomenology. I’ll provide a broad survey of generalized symmetries relevant to four-dimensional field theories and present two examples where these symmetries are relevant for axion physics. (No prior familiarity with generalized symmetries is assumed or required.)
