Running soft theorems in effective field theory
Jonah Berean-Dutcher, Maria Derda, Riley Stewart
We study soft theorems for photons and pions with local effective field theory (EFT) corrections up to one loop order. In massive QED with a dimension-five Pauli operator, the loca…

Parity Violating Marginal Deformation of the 3D Gross-Neveu-Thirring Model
Gordon W. Semenoff, Riley A. Stewart
A hybrid of the critical three dimensional Gross-Neveu and Thirring models deformed by explicit parity breaking operators is studied in the large N expansion and using the renormal…

Dilaton in a Multicritical 3+epsilon-D Parity Violating Field Theory
Gordon W. Semenoff, Riley A. Stewart
The multi-critical behaviour of an approximately scale and conformal invariant quantum field theory, which can be regarded as the deformation of the critical Gross-Neveu model in 3…
