Accelerating Feynman Integral Evaluation by Avoiding Contour Deformation
Stephen P. Jones, Anton Olsson, Thomas Stone
We describe our method for rewriting dimensionally regulated Feynman parameter integrals in the Minkowski regime as a sum of real, positive integrands multiplied by complex prefact…
Globally Optimal Contour Deformations with Neural Networks
Stephen Jones, Daniel Maître, Anton Olsson
In this article, we explore the use of contour deformation for the numerical evaluation of Feynman integrals after sector decomposition. In existing codes, the contour of integrati…
Positive Integrands from Feynman Integrals in the Minkowski Regime
Stephen Jones, Anton Olsson, Thomas Stone
We present a method for rewriting dimensionally regulated Feynman parameter integrals in the Minkowski regime as a sum of real, positive integrands multiplied by complex prefactors…
Evaluating Parametric Integrals in the Minkowski Regime without Contour Deformation
Stephen Jones, Anton Olsson, Thomas Stone
We present selected examples demonstrating an alternative approach to contour deformation for numerically computing loop integrals in the Minkowski regime. This method focuses on i…
ftint: Calculating gradient-flow integrals with pySecDec
Robert V. Harlander, Theodoros Nellopoulos, Anton Olsson +1
The program ftint is introduced which numerically evaluates dimensionally regulated integrals as they occur in the perturbative approach to the gradient-flow formalism in quantum f…
