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.
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
Constraining GRB parameters with KM3-230213A
22 September 2025 – We present a new paper with the title ‘Constraining gamma-ray burst parameters with the first ultra-high-energy neutrino KM3-230213A‘.
KM3NeT at the EPS-HEP conference
18 July 2025 – Last week, leading particle physicists gathered for the “EPS-HEP” biennial conference. This meeting, held by the High-Energy Physics division of the European Physical Society (EPS), is one of the biggest particle physics conferences in Europe. Read more
Atmospheric neutrino flux measured with ORCA6
15 July 2025 – The European Physical Journal C has accepted for publication a new KM3NeT paper with the title ‘Measurement of the atmospheric νμ flux with six detection units of KM3NeT/ORCA‘.
Scientific interest in KM3-230213A
14 June 2025 – It is about four months since we published our KM3-230213A event.
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.
