As the highest-energy neutrino event documented to date, its astrophysical origin remains unascertained. Prior preliminary investigations have probed potential associations between this neutrino event and gamma-ray bursts (GRBs), factoring in the possibility of Lorentz invariance violation (LV). In this study, we perform a comprehensive analysis to explore correlations between KM3-2"},"claims":{"count":4,"items":[{"kind":"strongest_claim","text":"Our analysis identifies a larger set of correlated GRBs.
