Monte Carlo evaluation of divergent one-loop integrals without contour deformation
Published 23 Apr 2024 in hep-ph and hep-th | (2404.14868v2)
Abstract: Reference [1] introduces a method for computing numerically four-dimensional multi-loop integrals without performing an explicit analytic contour deformation around threshold singularities. In this paper, we extend such a technique to massless scalar one-loop integrals regularized in the framework of dimensional regularization. A two-loop example is also discussed.
