Semi-Chiral Operators in 4d Gauge Theories
Kasia Budzik, Davide Gaiotto, Justin Kulp +3
We discuss the properties of quarter-BPS local operators in four dimensional supersymmetric Yang-Mills theory using the formalism of holomorphic twists. We study loop…
Universal Non-Invertible Symmetries
Lakshya Bhardwaj, Sakura Schafer-Nameki, Jingxiang Wu
It is well-known that gauging a finite 0-form symmetry in a quantum field theory leads to a dual symmetry generated by topological Wilson line defects. These are described by the r…
Feynman Diagrams in Four-Dimensional Holomorphic Theories and the Operatope
Kasia Budzik, Davide Gaiotto, Justin Kulp +2
We study a class of universal Feynman integrals which appear in four-dimensional holomorphic theories. We recast the integrals as the Fourier transform of a certain polytope in the…
Notes on Resonances and Unitarity from Celestial Amplitudes
Diego García-Sepúlveda, Alfredo Guevara, Justin Kulp +1
We study the celestial description of the sigma model in the large limit as introduced by Coleman, Jackiw and Politzer. Focusing on three dimensions, we analyze the impl…
Anisotropic Kondo line defect and ODE/IM correspondence
Jingxiang Wu
We study the anisotropic Kondo line defects in products of chiral WZW models. We propose an ODE/IM correspondence for the anisotropic Kondo problems by considering the four…
Kondo line defects and affine Gaudin models
Davide Gaiotto, Ji Hoon Lee, Benoit Vicedo +1
We describe the relation between integrable Kondo problems in products of chiral WZW models and affine Gaudin models. We propose a full ODE/IM solution of the spect…
