G. Abbiendi, A. Arbuzov, Sw. Banerjee +31
The mini-proceedings of the STRONG2020 Virtual Workshop "Space-like and Time-like determination of the Hadronic Leading Order contribution to the Muon ", November 24--26 2021,…
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…
Vector Space of Feynman Integrals and Multivariate Intersection Numbers
Hjalte Frellesvig, Federico Gasparotto, Manoj K. Mandal +3
Feynman integrals obey linear relations governed by intersection numbers, which act as scalar products between vector spaces. We present a general algorithm for constructing multiv…
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…
Top-quark effects in diphoton production through gluon fusion at NLO in QCD
Fabio Maltoni, Manoj K. Mandal, Xiaoran Zhao
At hadron colliders, the leading production mechanism for a pair of photons is from quark-anti-quark annihilation at the tree level. However, due to large gluon-gluon luminosity, t…
Evaluating multi-loop Feynman integrals numerically through differential equations
Manoj K. Mandal, Xiaoran Zhao
The computation of Feynman integrals is often the bottleneck of multi-loop calculations. We propose and implement a new method to efficiently evaluate such integrals in the physica…
