KM3NeT - KM3NeT

The KM3NeT Collaboration met in Bratislava!

19 June 2026 – The KM3NeT Collaboration gathered last week in Bratislava, Slovakia, for an inspiring Collaboration meeting.

The meeting had a vibrant program, which included a detailed review of the status of construction of the ARCA and ORCA detectors, a refinement of plans for integration and installation, discussion of new ideas for calibration, reports on a variety of ongoing analyses and also hands-on sections devoted to key steps in data processing and analysis.
The results from several analyses were scrutinised in preparation to next conferences. And interesting developments were reported in many fields, ranging from handling of real-time alerts to multimessenger searches.

During the meeting, the KM3NeT Collaboration was pleased to accept the application of Würzburg University (Germany) to become full member of the collaboration.

Finally, the executive board of the recently established AISBL also met and a discussion was organised on how to harmonise the activities of the AISBL with the other bodies of the Collaboration.

The Collaboration is deeply grateful to the local KM3NeT team in Bratislava for organising an excellent meeting.

Next Collaboration meeting: in Siracusa, Italy, in October.


Welcome, ORCA-38!

20 April 2026 – A very successful sea operation took place last week, leading to a new extension of the ORCA submarine telescope off the coast of Toulon, France. Read more


Lorentz invariance

10 March 2026 – We present a new paper with the title ‘Atmospheric neutrino constraints on Lorentz invariance violation with the first six detection units of KM3NeT/ORCA’.

In the paper, we describe our search for the violation of isotropic Lorentz invariance using 1.4 years of atmospheric neutrino data collected with ORCA6 – the first six detection units of the ORCA detector. Read more





KM3NeT Bootcamp brings newcomers together

26th January 2026 – The 2026 KM3NeT Bootcamp was held at the Faculty of Science, in Granada, from January 20th to January 23rd, bringing together newcomers to the collaboration for an intensive introduction to KM3NeT. Read more


Blazar origin of KM3-230213A?

21 November 2025 – We present a new paper with the title ‘Blazars as a Potential Origin of the KM3-230213A Event‘.

In the paper, we test the hypothesis that the ultra-high-energy neutrino KM3-230213A could come from the diffuse neutrino emission of blazars. Read more
