A.Decay of superluminal neutrinos in the collinear approximationART-2023-133038The kinematics of the three-body decay, with a modified energy-momentum relation of the particles due to a violation of Lorentz invariance, is presented in detail in the collinear approximation. The results are applied to the decay of superluminal neutrinos producing an electron-positron or a neutrino-antineutrino pair. Explicit expressions for the energy distributions, required for a study of the cascade of neutrinos produced in the propagation of superluminal neutrinos, are derived.2023http://zaguan.unizar.es/record/12528610.1103/PhysRevD.107.043001http://zaguan.unizar.es/record/125286oai:zaguan.unizar.es:125286info:eu-repo/grantAgreement/ES/AEI/PID2019-106802GB-I00info:eu-repo/grantAgreement/ES/AEI/PRE2019-089024info:eu-repo/grantAgreement/EUR/COST-Action/CA18108info:eu-repo/grantAgreement/ES/DGA-FSE/E21-17Rinfo:eu-repo/grantAgreement/ES/MCI-AEI-FEDER/PGC2018-095328-B-I00Physical Review D 107, 4 (2023), 043001 [12 pp.]byhttp://creativecommons.org/licenses/by/3.0/es/info:eu-repo/semantics/openAccess
