Multi-Loop Negative Geometries
Lance J. Dixon, Umut Oktem, Shruti Paranjape +3
Scattering amplitudes in planar supersymmetric Yang-Mills theory are dual to expectation values of null polygonal Wilson loops. The Amplituhedron provides a geometric…
Three-loop pentagonal Wilson loop with Lagrangian insertion
Dmitry Chicherin, Johannes Henn, Yongqun Xu +2
Employing a cutting-edge bootstrap method, we analytically compute the three-loop pentagonal Wilson loop with Lagrangian insertion in planar super-Yang-Mills theory…
Complete computation of all three-loop five-point massless planar integrals
Dmitry Chicherin, Yu Wu, Zihao Wu +3
We calculate all three-loop, five-point, massless planar Feynman integral families in the dimensional regularization scheme. This is a new milestone in Feynman integral computation…
Two-Loop Spacelike Splitting Amplitude for N=4 Super-Yang-Mills Theory
Johannes Henn, Rourou Ma, Yongqun Xu +3
The study of collinear behavior for gauge theories in the spacelike region is of great phenomenological and theoretical importance. We analytically calculate the two-loop spacelike…
