At the classical level, this modification is required when one considers a model including single- or multi-interaction processes, for which absolute locality in terms of canonical spacetime coordinates is lost. We discuss the different alternatives for observable effects in the propagation of a particle over very large distances that emerge from the new notion of spacetime. A central ingredient in the discussion is the cluster decomposition principle, which can be used to favor some alternatives over the others. 000087747 536__ $$9info:eu-repo/grantAgreement/ES/DGIID-DGA/2015-E24-2$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/PGC2018-095328-B-I00 000087747 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000087747 590__ $$a2.645$$b2019 000087747 591__ $$aMULTIDISCIPLINARY SCIENCES$$b29 / 71 = 0.408$$c2019$$dQ2$$eT2 000087747 592__ $$a0.365$$b2019 000087747 593__ $$aChemistry (miscellaneous)$$c2019$$dQ2 000087747 593__ $$aComputer Science (miscellaneous)$$c2019$$dQ2 000087747 593__ $$aMathematics (miscellaneous)$$c2019$$dQ3 000087747 593__ $$aPhysics and Astronomy (miscellaneous)$$c2019$$dQ3 000087747 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000087747 700__ $$0(orcid)0000-0002-8282-3435$$aCortés, José Luis$$uUniversidad de Zaragoza 000087747 700__ $$0(orcid)0000-0003-1130-3982$$aRelancio, José Javier$$uUniversidad de Zaragoza 000087747 7102_ $$12004$$2405$$aUniversidad de Zaragoza$$bDpto.
