KM3NeT - Research
Highlights during day-to-day KM3NeT research activities such as pitches for new papers, talks and posters during international conferences and (internal) workshops, comments on events in astroparticle physics and particle physics etc.
A set of dedicated studies on KM3-230213A
20 February 2025 – Recently the KM3NeT Collaboration has published evidence for the cosmic neutrino with the highest energy ever detected (the article on Nature can be accessed from here). This event is identified as KM3-230213A.
In a set of dedicated studies, the Collaboration has investigated the possible sources of the event and the implications that may be derived from it.
Observation of an ultra-high-energy cosmic neutrino with KM3NeT
On February 12, 2025, The KM3NeT Collaboration has announced the detection from the abyss of the Mediterranean Sea of a cosmic neutrino with a record-breaking energy of about 220 PeV.

Probing for invisible neutrino decay with ORCA6
3 February 2025 – In a new paper with the title ‘Probing invisible neutrino decay with the first six detection units of KM3NeT/ORCA’ we presents the results of a search for signs of invisible neutrino decay.
Search for non-standard neutrino interactions with ORCA6
29 November 2024 – In a new paper with the title ‘Search for non-standard neutrino interactions with the first six detection units of KM3NeT/ORCA‘ we search for Non-Standard Interactions (NSI) by investigating distortions of the standard oscillation pattern of neutrinos of all flavours.
Update of gSeaGen simulation software
23 November 2024 – In a new paper with the title ‘gSeaGen code by KM3NeT: an efficient tool to propagate muons simulated with CORSIKA’ we describe an open source solution for efficient simulation of cosmic-ray induced muons in neutrino telescopes.
Astronomy potential of ARCA
22 November 2024 – In a paper with the title ‘Astronomy potential of KM3NeT/ARCA’ we present improvements that indeed enhance the astronomy potential of the ARCA detector.
First searches for Dark Matter
20 November 2024 – In a new paper with the title ‘First searches for Dark Matter with the KM3NeT Neutrino Telescopes’ we present limits for neutrino production by Dark Matter annihilation in the Sun and the Galactic Centre. For the analysis we used the data of early configurations of the ARCA and ORCA detectors of KM3NeT.
