Tree-Level Factorization Obstruction in Monopole Production
Hsing-Yi Lai, John Terning
We show that the tree-level amplitude for producing a monopole--antimonopole pair from an electrically charged pair cannot be constructed from the minimal one-photon couplings. Glu…
Non-invertible Chiral Symmetry and Axions under Electromagnetic Duality
Gongjun Choi, Tony Gherghetta, John Terning
We study the implications of non-invertible chiral symmetry in a four-dimensional U(1) gauge theory coupled to massless fermions with electromagnetic duality. Th…
Geometrizing the Anomaly
Joshua Newey, John Terning, Christopher B. Verhaaren
Recently a manifestly gauge invariant formalism for calculating amplitudes in quantum electrodynamics was outlined in which the field strength, rather than the gauge potential, is…
The Seiberg-Witten Axion
Csaba Csáki, Rotem Ovadia, Maximilian Ruhdorfer +2
We present a fully calculable UV complete toy model of a Peccei-Quinn (PQ) axion coupled to magnetic monopoles as well as electric charges. The theory has manifest electric-magneti…
Schwinger vs Coleman: Magnetic Charge Renormalization
Joshua Newey, John Terning, Christopher B. Verhaaren
The kinetic mixing of two U(1) gauge theories can result in a massless photon that has perturbative couplings to both electric and magnetic charges. This framework can be used to p…
