We are delighted to announce the upcoming High-Energy Theory Seminar by Dr. Seth Koren visiting us from University of Notre Dame.
The seminar will take place today Tuesday (Dec 19) at 4PM at E6-2, #1323 and you are all invited to participate. 
Speaker: Seth Koren (University of Notre Dame)
Time: December 19 (Tuesday), 4PM
Place: E6-2, #1323
Title: Non-invertible symmetries, leptons, quarks, and why multiple generations
Generalized global symmetries are present in theories of particle physics, and understanding their structure can give insight into these theories and UV completions thereof.  We will particularly discuss the use of non-invertible chiral symmetries in BSM model-building. The identification of a non-invertible symmetry in Z' models of L_µ - L_τ reveals the existence of non-Abelian horizontal gauge theories which naturally produce exponentially small Dirac neutrino masses. Next we will uncover a subtler non-invertible symmetry in horizontal gauge theories of the quark sector which will lead us to a massless down-type quarks solution to strong CP in color-flavor unification. Intriguingly, this symmetry is present by virtue of the SM having the same numbers of colors and generations.
