Functions Beyond Multiple Polylogarithms for Precision Collider Physics
Jacob L. Bourjaily, Johannes Broedel, Ekta Chaubey +14
Feynman diagrams constitute one of the essential ingredients for making precision predictions for collider experiments. Yet, while the simplest Feynman diagrams can be evaluated in…
Cuts and Isogenies
Hjalte Frellesvig, Cristian Vergu, Matthias Volk +1
We consider the genus-one curves which arise in the cuts of the sunrise and in the elliptic double-box Feynman integrals. We compute and compare invariants of these curves in a num…
On the Application of Intersection Theory to Feynman Integrals: The Univariate Case
Hjalte Frellesvig, Luca Mattiazzi
This document is a contribution to the proceedings of the MathemAmplitudes 2019 conference held in December 2019 in Padova, Italy. A key step in modern high energy physics scatteri…
Decomposition of Feynman Integrals by Multivariate Intersection Numbers
Hjalte Frellesvig, Federico Gasparotto, Stefano Laporta +4
We present a detailed description of the recent idea for a direct decomposition of Feynman integrals onto a basis of master integrals by projections, as well as a direct derivation…
Two-Loop QCD-EW Master Integrals for Z Plus Jet Production at Large Transverse Momentum
Hjalte Frellesvig, Kirill Kudashkin, Christopher Wever
The production of electroweak bosons that decay to neutrinos and recoil against jets with large transverse momentum is an important background process to searches for…
The complete set of two-loop master integrals for Higgs + jet production in QCD
Hjalte Frellesvig, Martijn Hidding, Leila Maestri +2
In this paper we complete the computation of the two-loop master integrals relevant for Higgs plus one jet production initiated in arXiv:1609.06685, arXiv:1907.13156, arXiv:1907.13…
