Massive Integrability: From Fishnet Theories to Feynman Graphs and Back

TL;DR

This paper explores the extension of Yangian symmetry to massive Feynman integrals, connecting fishnet theories with Feynman graphs through a double-scaling limit of N=4 SYM.

Contribution

It introduces a massive generalization of Yangian symmetry and links fishnet theories to Feynman graphs via a specific limit of N=4 SYM.

Findings

Massive Yangian symmetry applies to Feynman integrals.

Connection established between fishnet theories and Feynman graphs.

Double-scaling limit of N=4 SYM leads to a massive fishnet theory.

Abstract

An overview of the massive generalization of Yangian symmetry for Feynman integrals is given. We illustrate the relation to a massive fishnet theory defined as a double-scaling limit of Coulomb-branch N=4 SYM theory.
