Neutrino Masses from Generalized Symmetry Breaking

Clay Cordova, Sungwoo Hong, Seth Koren +1

We explore generalized global symmetries in theories of physics beyond the Standard Model. Theories of bosons generically contain 'non-invertible' chiral symmetries, whose pre…

Matching higher symmetries across Intriligator-Seiberg duality

Yasunori Lee, Kantaro Ohmori, Yuji Tachikawa

We study higher symmetries and anomalies of 4d gauge theory with flavors. We find that they depend on the parity of and , the global form of…

6d/5d exceptional gauge theories from web diagrams

Hirotaka Hayashi, Hee-Cheol Kim, Kantaro Ohmori

We construct novel web diagrams with a trivalent or quadrivalent gluing for various 6d/5d theories from certain Higgsings of 6d conformal matter theories on a circle. The theories…

Replica Instantons from Axion-like Coupling

Kantaro Ohmori

We find a phenomenon in a non-gravitational gauge theory analogous to the replica wormhole in a quantum gravity theory. We consider a reservoir of a scalar field coupled with a gau…

Revisiting Wess-Zumino-Witten terms

Yasunori Lee, Kantaro Ohmori, Yuji Tachikawa

We revisit various topological issues concerning four-dimensional ungauged and gauged Wess-Zumino-Witten (WZW) terms for and quantum chromodynamics (QCD), from the modern…

Anomaly Constraints on Gapped Phases with Discrete Chiral Symmetry

Clay Cordova, Kantaro Ohmori

We prove that in quantum field theories with symmetry, certain anomalies forbid a symmetry-preserving vacuum state with a gapped spectrum. In particular, th…
