Universidad de Zaragoza (orcid)0000-0003-2264-2306 Consistency of Lorentz-invariance violation neutrino scenarios in time delay analyses 2024 Access copy available to the general public Unrestricted Modifications inspired by quantum gravity in the kinematics of special relativity can manifest in various ways, including anomalies in the time of flight of massless particles and the emergence of decay channels for otherwise stable particles. Typically, these effects are studied independently; however, it may be necessary to combine both to perform a consistent analysis. In this work, we study the interplay between time-of-flight anomalies and neutrino instability in the context of a flavour-independent high-energy Lorentz-invariance violation (LIV) in the neutrino sector. Ensuring compatibility between both types of effects imposes strong constraints on the existence of early neutrinos with energies exceeding a maximum value determined by the scale of new physics. Such constraints depend on the specific LIV scenario and should be integrated into searches for high-energy neutrinos from gamma-ray bursts exhibiting LIV time shifts. info:eu-repo/grantAgreement/ES/AEI/PID2021-126078NB-C21 info:eu-repo/grantAgreement/ES/AEI/PRE2019-089024 info:eu-repo/grantAgreement/ES/DGA/E21-23R info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 3.7 2024 PHYSICS, MULTIDISCIPLINARY 27 / 114 = 0.237 2024 Q1 T1 QUANTUM SCIENCE & TECHNOLOGY 14 / 28 = 0.5 2024 Q2 T2 PHYSICS, PARTICLES & FIELDS 10 / 31 = 0.323 2024 Q2 T1 ASTRONOMY & ASTROPHYSICS 25 / 84 = 0.298 2024 Q2 T1 1.154 2024 Physics and Astronomy (miscellaneous) 2024 Q1 7.0 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Cortés, J.
