Title: Broken higher-form symmetries in particle physics
 
Abstract: The study of generalized symmetries has led to new insights across high energy, condensed matter, and mathematical physics, but we are still in the early days of applications to particle physics. In this talk, I’ll briefly survey some of the generalized symmetries relevant for particle physics and present two examples where broken higher-form symmetries shed new light on phenomenology: the quality problem for extra-dimensional axions, and the quantum violation of baryon number in classically baryon-conserving unified theories. Both examples have novel astrophysical and cosmological implications. No prior familiarity with generalized symmetries is assumed or required.
