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.

First call opened for transnational access to KM3NeT data

8 April 2026 – The first call for proposals for science projects based on KM3NeT data proposed by external users is open!

The call and ACME – This call is opened in the framework of ACME. The ACME project enables transnational access (TA) on the basis of scientific merit to a wide range of complementary astroparticle, high-energy and astronomical Research Infrastructures to perform new science of multi-messenger astrophysics.

For more information on ACME see the ACME portal.

How to prepare a proposal – This call is open to all external users, with no restriction. External scientists may act as Principal Investigators (PI) or co-Investigators (coI) on the proposals, provided they agree to a Non-Disclosure Agreement with the KM3NeT collaboration. The proposals will be evaluated in a blind procedure by a Program Committee, comprising members from both KM3NeT and the Pierre Auger Collaborations. The proposals will have to be presented in two documents: a proposal description and a team description.

More information on the call:

The deadline for submission is on May 22nd, 2026, 12:00 UTC.

For all details on how to prepare a proposal, you can check the full text of the call.

Find the template of the two documents to prepare here: templates of proposal and team documents.

Non-disclosure Agreement: NDA template.

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

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

New paper about deep-sea turbulence

17 October 2025 – We present a new paper with the title ‘Whipped and mixed warm clouds in the deep sea‘.

With a unique array of high-resolution temperature sensors we studied the turbulence in the deep sea, for the first time in 3D.

Search for sterile neutrinos with ORCA6

13 October 2025 – We present a new paper with the title ‘‘Search for an eV-scale sterile neutrino with the first six detection units of KM3NeT/ORCA“.

Sterile neutrinos are hypothetical neutrinos proposed by theoretical physicists to explain unexpected experimental results obtained over the course of the past 25 years. Read more

The Online Data Filter for the KM3NeT Neutrino Telescopes

10 June 2025 – Recently, we submitted a new paper with the title ‘The Online Data Filter for the KM3NeT Neutrino Telescopes’

In this paper, we present the design and performance of the software that is used to filter the data recorded by the photo-sensors of the KM3NeT detectors.
