They reinforce the contention that local symmetry emerges directly from quantum theory, but global gauge invariance remains in general an unwarranted assumption to be examined case by case. Armed with those modern tools, we reconsider here the classical Okubo– Marshak argument on the non-existence of a “strong CP problem” in quantum chromodynamics. 000151134 536__ $$9info:eu-repo/grantAgreement/EUR/COST-Action/CA18108$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/PGC2018-095328-B-I00 000151134 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttps://creativecommons.org/licenses/by/4.0/deed.es 000151134 590__ $$a2.94$$b2021 000151134 591__ $$aMULTIDISCIPLINARY SCIENCES$$b34 / 74 = 0.459$$c2021$$dQ2$$eT2 000151134 592__ $$a0.54$$b2021 000151134 593__ $$aChemistry (miscellaneous)$$c2021$$dQ2 000151134 593__ $$aPhysics and Astronomy (miscellaneous)$$c2021$$dQ2 000151134 593__ $$aComputer Science (miscellaneous)$$c2021$$dQ2 000151134 594__ $$a4.3$$b2021 000151134 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000151134 700__ $$0(orcid)0000-0002-8036-4589$$aGracia-Bondía J.M.$$uUniversidad de Zaragoza 000151134 700__ $$aMund J. 000151134 7102_ $$12004$$2405$$aUniversidad de Zaragoza$$bDpto.
