To a large extent, the controversy turned around the respective merits of the regularization techniques employed. The novel aspect of our approach is that no regularization techniques are brought to bear: we work within the Bogoliubov–Epstein–Glaser scheme of renormalization by extension of distributions. Solving the problem actually required an expansion of this method’s toolkit, furnished in the paper. 000099774 536__ $$9info:eu-repo/grantAgreement/EUR/COST-Action/CA18108$$9info:eu-repo/grantAgreement/EC/H2020/690575/EU/InvisiblesPlus/InvisiblesPlus$$9This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 690575-InvisiblesPlus$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/FPA2015-65745-P 000099774 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000099774 590__ $$a4.994$$b2021 000099774 592__ $$a1.563$$b2021 000099774 594__ $$a8.3$$b2021 000099774 591__ $$aPHYSICS, PARTICLES & FIELDS$$b8 / 29 = 0.276$$c2021$$dQ2$$eT1 000099774 593__ $$aPhysics and Astronomy (miscellaneous)$$c2021$$dQ1 000099774 593__ $$aEngineering (miscellaneous)$$c2021$$dQ1 000099774 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000099774 700__ $$aDütsch, M. 000099774 700__ $$0(orcid)0000-0002-8036-4589$$aGracia-Bondía, J.M.$$uUniversidad de Zaragoza 000099774 7102_ $$12004$$2405$$aUniversidad de Zaragoza$$bDpto.
