Universidad de Zaragoza (orcid)0000-0003-2264-2306 Time delays, choice of energy-momentum variables, and relative locality in doubly special relativity 2022 Access copy available to the general public Unrestricted Doubly special relativity (DSR) theories consider (quantum-gravity motivated) deformations of the symmetries of special relativity compatible with a relativity principle. The existence of time delays for massless particles, one of their proposed phenomenological consequences, is a delicate question since, contrary to what happens with Lorentz invariance violation scenarios, they are not simply determined by the modification in the particle dispersion relation. While some studies of DSR assert the existence of photon time delays, in this paper we generalize a recently proposed model for time delay studies in DSR and show that the existence of photon time delays does not necessarily follow from a DSR scenario, determining in which cases this is so. Moreover, we clarify long-standing questions about the arbitrariness in the choice of the energy-momentum labels and the independence of the time delay on this choice, as well as on the consistency of its calculation with the relative locality paradigm of DSR theories. Finally, we show that the result for time delays is reproduced in models that consider propagation in a noncommutative spacetime. info:eu-repo/grantAgreement/ES/AEI/PID2019-106802GB-I00 info:eu-repo/grantAgreement/ES/AEI/PRE2019-089024 info:eu-repo/grantAgreement/EUR/COST-Action/CA18108 info:eu-repo/grantAgreement/ES/DGA-FSE/E21-17R info:eu-repo/grantAgreement/ES/MCI-AEI-FEDER/PGC2018-095328-B-I00 info:eu-repo/grantAgreement/ES/MCIN/AEI/10.13039/501100011033 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 5.0 2022 PHYSICS, PARTICLES & FIELDS 7 / 29 = 0.241 2022 Q1 T1 ASTRONOMY & ASTROPHYSICS 15 / 69 = 0.217 2022 Q1 T1 1.639 2022 Physics and Astronomy (miscellaneous) 2022 Q1 Nuclear and High Energy Physics 2022 Q1 9.2 2022 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Cortés, J.L.
