dc.description.abstract	Reference (Pittau and Webber in Eur Phys J C 82(1):55, https://doi.org/10.1140/epjc/s10052-022-10008-6, 2022) introduces a method for computing numerically fourdimensional 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.	es_ES
