Universidad de Zaragoza (orcid)0000-0003-2264-2306 Bounds on Relativistic Deformed Kinematics from the Physics of the Universe Transparency 2020 Access copy available to the general public Unrestricted We analyze the kinematics of electron-positron production in a photon-photon interaction when one has a modification of the special relativistic kinematics as a power expansion in the inverse of a new high-energy scale. We derive the equation for the threshold energy of this reaction to first order in this expansion, including the effects due to a modification of the energy-momentum conservation equation. In contrast with the Lorentz invariance violation case, a scale of the order of a few TeV is found to be compatible with the observations of very high-energy cosmic gamma rays in the case of a modification compatible with the relativity principle. info:eu-repo/grantAgreement/EUR/COST-Action/CA18108 info:eu-repo/grantAgreement/ES/DGA-FSE/E21-20R 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/ 2.713 2020 MULTIDISCIPLINARY SCIENCES 33 / 73 = 0.452 2020 Q2 T2 0.385 2020 Chemistry (miscellaneous) 2020 Q2 Physics and Astronomy (miscellaneous) 2020 Q2 Mathematics (miscellaneous) 2020 Q2 Computer Science (miscellaneous) 2020 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Cortes, J.L.
