Besides the absence of evanescent fields in IReg, such as -scalars required in certain schemes that operate partially in the physical dimension, we verify that our procedure preserves gauge invariance in the presence of the matrix without requiring symmetry preserving counterterms while the amplitude is infrared finite as stated by the KLN theorem.}, organization = {Fundação para a Ciência eTecnologia (FCT) through the projects CERN/FIS-PAR/0040 /2019, CERN /FIS-COM /0035 /2019, UID /FIS /04564 /2020, and the grant FCT 2020.07172.BD}, organization = {National Council for Scientific and Technological Development - CNPq through projects 166523/2020-8 and 201013/2022-3}, organization = {CNPq through grant 302790/2020-9}, publisher = {Springer Nature}, title = {Infrared subtleties and chiral vertices at NLO: an implicit regularization analysis}, doi = {10.1140/epjc/s10052-023-12052-2}, author = {Rosado, Ricardo J.
