Two-loop Vertices with Vacuum Polarization Insertion
Taushif Ahmed, Giulio Crisanti, Federico Gasparotto +2
We present the analytic evaluation of the second-order corrections to the massive form factors, due to two-loop vertex diagrams with a vacuum polarization insertion, with exact dep…
calculations for processes using Simplified Differential Equations
Dhimiter D. Canko, Federico Gasparotto, Luca Mattiazzi +2
We present the computation of the massless three-loop ladder-box family with one external off-shell leg using the Simplified Differential Equations (SDE) approach. We also discuss…
Two-photon exchange in leptophilic dark matter scenarios
Raghuveer Garani, Federico Gasparotto, Pierpaolo Mastrolia +3
In leptophilic scenarios, dark matter interactions with nuclei, relevant for direct detection experiments and for the capture by celestial objects, could only occur via loop-induce…
Decomposition of Feynman Integrals on the Maximal Cut by Intersection Numbers
Hjalte Frellesvig, Federico Gasparotto, Stefano Laporta +4
We elaborate on the recent idea of a direct decomposition of Feynman integrals onto a basis of master integrals on maximal cuts using intersection numbers. We begin by showing an a…
