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. info:eu-repo/grantAgreement/ES/DGIID-DGA/2015-E24-2 info:eu-repo/grantAgreement/ES/MINECO-FEDER/PGC2018-095328-B-I00 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.645 2019 MULTIDISCIPLINARY SCIENCES 29 / 71 = 0.408 2019 Q2 T2 0.365 2019 Chemistry (miscellaneous) 2019 Q2 Computer Science (miscellaneous) 2019 Q2 Mathematics (miscellaneous) 2019 Q3 Physics and Astronomy (miscellaneous) 2019 Q3 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Cortés, José Luis Universidad de Zaragoza (orcid)0000-0002-8282-3435 Relancio, José Javier Universidad de Zaragoza (orcid)0000-0003-1130-3982 2004 405 Universidad de Zaragoza Dpto.
