Constraining gamma-ray burst parameters with the first ultra-high energy neutrino event KM3-230213A
KM3NeT Collaboration, O. Adriani, A. Albert +278
Context: The detection of the highest energy neutrino observed to date by KM3NeT, with an estimated energy of 220 PeV, opens up new possibilities for the study and identification o…
Constraints on the diffuse flux of multi-PeV astrophysical neutrinos obtained with the Baikal Gigaton Volume Detector
V. A. Allakhverdyan, A. D. Avrorin, A. V. Avrorin +69
Various theoretical models predict cosmic neutrinos with multi-PeV energies. The recent detection of a ~10^17 eV neutrino in the KM3NeT experiment suggests that these energetic par…
Measurement of the diffuse astrophysical neutrino flux over six seasons using cascade events from the Baikal-GVD expanding telescope
GVD Collaboration, V. A. Allakhverdyan, A. D. Avrorin +67
We present an updated measurement of the diffuse astrophysical neutrino flux using Baikal-GVD cascade data collected between April 2018 to March 2024. In this period, the detector…
KM3NeT Constraint on Lorentz-Violating Superluminal Neutrino Velocity
KM3NeT Collaboration, O. Adriani, S. Aiello +290
Lorentz invariance is a fundamental symmetry of spacetime and foundational to modern physics. One of its most important consequences is the constancy of the speed of light. This in…
On the Potential Galactic Origin of the Ultra-High-Energy Event KM3-230213A
O. Adriani, S. Aiello, A. Albert +286
The KM3NeT observatory detected the most energetic neutrino candidate ever observed, with an energy between 72 PeV and 2.6 EeV at the 90% confidence level. The observed neutrino is…
The ultra-high-energy event KM3-230213A within the global neutrino landscape
KM3NeT Collaboration, O. Adriani, S. Aiello +290
On February 13th, 2023, the KM3NeT/ARCA telescope detected a neutrino candidate with an estimated energy in the hundreds of PeVs. In this article, the observation of this ultra-hig…
