Quite recently\, my collaborators and I have established positively that past being a useful formal tool\, such generalized symmetries are indeed p resent in models that we care about as particle physicists---and furthermo re understanding them can lead to new insights into these models. As a fir st example\, the Standard Model itself has a 'higher-group' symmetry inter twining flavor and hypercharge\, and I will discuss how this symmetry cont rols the structure of unification. Going Beyond\, I will show that the ide ntification of a 'non-invertible' symmetry of Z' models of L_µ - L_τ rev eals the existence of simple UV completions thereof where the scale of neu trino masses is exponentially suppressed from that of charged leptons.\n LOCATION:https://researchseminars.org/talk/nhetc/76/ END:VEVENT END:VCALENDAR
