-like Flows of Yang-Mills Theories
Christian Ferko, Jue Hou, Tommaso Morone +2
We study -like deformations of Yang-Mills theories. The standard flows lead to multi-trace Lagrangians, and the non-Abelian gauge structure…
Auxiliary Field Deformations of (Semi-)Symmetric Space Sigma Models
Daniele Bielli, Christian Ferko, Liam Smith +1
We generalize the auxiliary field deformations of the principal chiral model (PCM) introduced in arXiv:2405.05899 and arXiv:2407.16338 to sigma models whose target manifolds are sy…
Integrable Higher-Spin Deformations of Sigma Models from Auxiliary Fields
Daniele Bielli, Christian Ferko, Liam Smith +1
We construct a new infinite family of integrable deformations of the principal chiral model (PCM) parameterized by an interaction function of several variables, which extends the f…
T-Duality and -like Deformations of Sigma Models
Daniele Bielli, Christian Ferko, Liam Smith +1
We initiate the study of the interplay between T-duality and classical stress tensor deformations in two-dimensional sigma models. We first show that a general Abelian T-duality co…
Supersymmetry and Irrelevant Deformations
Christian Ferko
The operator provides a universal irrelevant deformation of two-dimensional quantum field theories with remarkable properties, including connections to both string…
