Association of 220 PeV Neutrino KM3-230213A with Gamma-Ray Bursts
Abstract
Recently, the KM3NeT Collaboration announced the detection of a 220 PeV neutrino from the celestial coordinates RA=94.3~ and Dec=-7.8~ on 13 February 2023 at 01:16:47 UTC KM3NeT:2025npi. The source for this extra-ordinary cosmic neutrino, designated KM3-230213A, is not identified yet but there has been speculation that it might be associated with a gamma-ray burst GRB~090401B Amelino-Camelia:2025lqn. The purpose of this report is to search the association of this 220 PeV neutrino with potential GRB sources from a more general consideration of Lorentz invariance violation (LV) without predefined LV scale. We try to associate this extra-ordinary neutrino with potential GRBs within angular separation of 1, 3~ and 5~ respectively and the results are listed in Table 1. We find the constraints ELV≤ 5.3× 1018~GeV for subluminal LV violation and ELV≤ 5.6× 1019~GeV for superluminal LV violation if KM3-230213A is a GRB neutrino.
