Gluing via Intersection Theory

Author(s): Giulio Crisanti, Burkhard Eden, Maximilian Gottwald, Pierpaolo Mastrolia, and Tobias Scherdin Higher-point functions in $\mathcal{N}=4$ super Yang-Mills theory can be constructed using integrability by triangulating the surfaces on which Feynman graphs would be drawn. It remains hard to analytically compute the necessary regluing of the tiles by virtual particles. We propose a new approach t… [Phys. Rev. Lett. 134, 251603] Published Thu Jun 26, 2025
