Approximating Feynman integrals using complete monotonicity and Stieltjes properties
Sara Ditsch, Johannes M. Henn, Prashanth Raman
We present two novel approaches for the numerical evaluation of Feynman integrals based on their universal analytic properties related to positivity, namely complete monotonicity (…

Approximating Feynman Integrals Using Complete Monotonicity and Stieltjes Properties
Sara Ditsch, Johannes M. Henn, Prashanth Raman
We introduce two novel numerical approaches for computing Feynman integrals based on their complete monotonicity (CM) and Stieltjes properties. The first method uses that scalar Fe…

One-Loop QCD Corrections to at
Matteo Becchetti, Maximilian Delto, Sara Ditsch +3
We present a computation of the one-loop QCD corrections to top-quark pair production in association with a boson, including terms up to order in dimensional re…
