Quark Anti-Quark Fusion and Walking RG Flows
Filipp Chernikov, Nikolay Gromov, Amit Sever
We study the fusion of two conjugate conformal line defects on the sphere. At small separation, their spectrum is governed by a universal Fusion Master Equation. Below a critical c…
Universal Constraints for Conformal Line Defects
Barak Gabai, Amit Sever, De-liang Zhong
We present a novel framework for deriving integral constraints for correlators on conformal line defects. These constraints emerge from the non-linearly realized ambient-space conf…
Correlators of Line Defect and Local Operator in Conformal Field Theories with a Slightly Broken Higher-Spin Symmetry
Gwenaël Ferrando, Amit Sever, Elior Urisman
We study three-dimensional conformal field theories with a large- limit. Leveraging the framework of slightly broken higher-spin symmetry, we bootstrap correlation functions bet…
Planar RG Flows on Line Defects
Ivri Nagar, Amit Sever, De-liang Zhong
We study a class of renormalization group flows on line defects that can be described by a generalized free field with ordered planar contractions on the line. They are realized, f…
Bootstrapping Smooth Conformal Defects in Chern-Simons-Matter Theories
Barak Gabai, Amit Sever, De-liang Zhong
The expectation value of a smooth conformal line defect in a CFT is a conformal invariant functional of its path in space-time. For example, in large holographic theories, thes…
