Search for an eV-scale sterile neutrino with the first six detection units of KM3NeT/ORCA Open
The existence of an eV-scale sterile neutrino has been proposed to explain several anomalous experimental results obtained over the course of the past 25 years. The first search for such a sterile neutrino conducted with data from KM3NeT/O…

Constraining the diffuse neutrino flux from gamma-ray burst blastwaves with the KM3-230213A ultra-high-energy event Open
KM3NeT/ARCA is a deep-sea Cherenkov neutrino telescope located 100 km off the coast of the southern tip of Sicily, Italy. When completed, the detector will instrument around one cubic kilometre of water with photodetectors to search for en…

Probing neutrino yield from different gamma-ray burst populations using the entire ANTARES data set Open
While the evidence of high-energy neutrinos was established a decade ago and confirmed independently by the observation of an ultra-high-energy neutrino recently announced, the origin of these neutrinos is not yet fully identified. Gamma-r…

Constraining gamma-ray burst parameters with the first ultra-high energy neutrino event KM3-230213A Open
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 of the astrophysical sources responsible for a diffuse flux …

Evaluation of the upgraded 3-inch Hamamatsu photomultiplier for the KM3NeT Neutrino Telescope Open
The 3-inch Hamamatsu R14374-02 photomultiplier tube is an improved version of the R12199-02 model and its successor in the construction of the KM3NeT neutrino telescope. A total of 1000 photomultipliers were analysed to assess their dark c…

Ultrahigh-Energy Event KM3-230213A within the Global Neutrino Landscape Open
On February 13th, 2023, the KM3NeT/ARCA telescope detected a neutrino candidate with an estimated energy in the hundreds of PeV. In this article, the observation of this ultrahigh-energy neutrino is discussed in light of null observations …

On the Potential Cosmogenic Origin of the Ultra-high-energy Event KM3-230213A Open
On 2023 February 13, the KM3NeT/ARCA telescope observed a track-like event compatible with a ultra-high-energy muon with an estimated energy of 120 PeV, produced by a neutrino with an even higher energy, making it the most energetic neutri…

Search for quantum decoherence in neutrino oscillations with six detection units of KM3NeT/ORCA Open
Neutrinos described as an open quantum system may interact with the environment which introduces stochastic perturbations to their quantum phase. This mechanism leads to a loss of coherence along the propagation of the neutrino - a phenome…

First searches for dark matter with the KM3NeT neutrino telescopes Open
Indirect dark matter detection methods are used to observe the products of dark matter annihilations or decays originating from astrophysical objects where large amounts of dark matter are thought to accumulate. With neutrino telescopes, a…

KM3NeT Constraint on Lorentz-Violating Superluminal Neutrino Velocity Open
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 invariance, together with the geometry of spacetime, implies …

Search for non-standard neutrino interactions with the first six detection units of KM3NeT/ORCA Open
KM3NeT/ORCA is an underwater neutrino telescope under construction in the Mediterranean Sea. Its primary scientific goal is to measure the atmospheric neutrino oscillation parameters and to determine the neutrino mass ordering. ORCA can co…

Search for Extremely-High-Energy Neutrinos and First Constraints on the Ultrahigh-Energy Cosmic-Ray Proton Fraction with IceCube Open
We present a search for the diffuse extremely-high-energy neutrino flux using 12.6 years of IceCube data. The nonobservation of neutrinos with energies well above 10 PeV constrains the all-flavor neutrino flux at 1018 eV to a level of $E^2…
Novel Hybrid Low-Resource Field-Programmable-Gate-Array Time-to-Digital-Converter Architecture Open
Time measurements are challenging in electronics given their various applications. The main focus lies not in achieving greater precision, as conventional architectures have already reached picosecond levels. Instead, the challenge stems f…
