Two-loop Six-point Planar Massless Feynman Integrals to Higher Orders
Yuanche Liu, Antonela MatijaÅ¡iÄ, Tiziano Peraro +3
In this work, we calculate two-loop six-point planar massless Feynman integrals at higher orders in the dimensional regulator , corresponding to higher transcendental weights.…
Perturbative bootstrap of the Wilson-line defect CFT: Bulk-defect-defect correlators
Daniele Artico, Julien Barrat, Yingxuan Xu
We study the correlators of bulk and defect half-BPS operators in Super Yang-Mills theory with a Maldacena-Wilson line defect, focusing on the case involving one bu…
Uncovering Singularities in Feynman Integrals via Machine Learning
Yuanche Liu, Yingxuan Xu, Yang Zhang
We introduce a machine-learning framework based on symbolic regression to extract the full symbol alphabet of multi-loop Feynman integrals. By targeting the analytic structure rath…
Performing integration-by-parts reductions using NeatIBP 1.1 + Kira
Zihao Wu, Janko Böhm, Rourou Ma +3
We introduce a new version v1.1 of NeatIBP. In this new version, a Kira interface is included. It allows the user to reduce the integration-by-parts (IBP) identity systems generate…
Complete function space for planar two-loop six-particle scattering amplitudes
Johannes Henn, Antonela MatijaÅ¡iÄ, Julian Miczajka +3
We derive the full system of canonical differential equations for all planar two-loop massless six-particle master integrals, and determine analytically the boundary conditions. Th…
An Analytic Computation of Three-Loop Five-Point Feynman Integrals
Yuanche Liu, Antonela MatijaÅ¡iÄ, Julian Miczajka +3
We evaluate the three-loop five-point pentagon-box-box massless integral family in the dimensional regularization scheme, via canonical differential equation. We use tools from com…
