KM3NeT constraint on Lorentz-violating superluminal neutrino velocity

Oscar Adriani, Stefano Aiello, A. Albert, A.R Alhebsi et autres

Abstract 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 that no particle can move …

Measurement of the atmospheric $$\nu _{\mu }$$ flux with six detection units of KM3NeT/ORCA

Stefano Aiello, A. Albert, A.R Alhebsi, M. Alshamsi et autres

Abstract A measurement of the atmospheric $$\nu _{\mu }+\bar{\nu }_{\mu }$$ ν μ + ν ¯ μ flux with energies between 1 and 100 GeV is presented. The measurement has been performed using data taken with the first six detection units of …

Evaluation of the upgraded 3-inch Hamamatsu photomultiplier for the KM3NeT Neutrino Telescope

Stefano Aiello, A. Albert, A.R Alhebsi, M. Alshamsi et autres

Abstract 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 count rate, transit time spread, …

Search for quantum decoherence in neutrino oscillations with six detection units of KM3NeT/ORCA

Stefano Aiello, Andrea Albert, A.R Alhebsi, M. Alshamsi et autres

Abstract 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 phenomenon commonly referred to as …

Measurement of neutrino oscillation parameters with the first six detection units of KM3NeT/ORCA

Stefano Aiello, Andrea Albert, A.R Alhebsi, M. Alshamsi et autres

A bstract KM3NeT/ORCA is a water Cherenkov neutrino detector under construction and anchored at the bottom of the Mediterranean Sea. The detector is designed to study oscillations of atmospheric neutrinos and determine the neutrino mass ordering. This paper focuses on an initial …

Search for neutrino emission from GRB 221009A using the KM3NeT ARCA and ORCA detectors

Stefano Aiello, A. Albert, M. Alshamsi, S. Alves Garre et autres

Abstract Gamma-ray bursts are promising candidate sources of high-energy astrophysical neutrinos. The recent GRB 221009A event, identified as the brightest gamma-ray burst ever detected, provides a unique opportunity to investigate hadronic emissions involving neutrinos. The KM3NeT undersea neutrino detectors participated in the …

Searches for neutrino counterparts of gravitational waves from the LIGO/Virgo third observing run with KM3NeT

Stefano Aiello, A. Albert, S. Alves Garre, Z. Aly et autres

The KM3NeT neutrino telescope is currently being deployed at two different sites in the Mediterranean Sea. First searches for astrophysical neutrinos have been performed using data taken with the partial detector configuration already in operation. The paper presents the results of two …

Follow-up of O3 gravitational wave events with neutrinos in ANTARES and KM3NeT telescopes

M. Lamoureux, A. Albert, S. Alves, M. André et autres

Astrophysical neutrinos may be produced during the coalescence of compact objects, in particular those involving neutron stars. Such mergers have been identified through gravitational wave detections by the LIGO and Virgo collaborations and reported in published catalogs. The ANTARES and KM3NeT deep-sea …

Hint for a TeV neutrino emission from the Galactic Ridge with the ANTARES telescope

M. Lamoureux, Antares, A. Albert, S. Alves et autres

The central region of our Galaxy (Galactic Ridge) is expected to produce a neutrino flux comparable to the one detected in $\gamma$ rays by Fermi, assuming these result from hadronic collisions of cosmic rays within the interstellar medium. Data collected by the …

Hint for a TeV neutrino emission from the Galactic Ridge with ANTARES

A. Albert, S. Alves, Michel L. Andre, M. Ardid et autres

Interactions of cosmic ray protons, atomic nuclei, and electrons in the interstellar medium in the inner part of the Milky Way produce a γ-ray flux from the Galactic Ridge. If the γ-ray emission is dominated by proton and nuclei interactions, a neutrino …

Probing invisible neutrino decay with KM3NeT/ORCA

S. Aiello, A. Albert, S. Alves Garre, Z. Aly et autres

Abstract In the era of precision measurements of the neutrino oscillation parameters, upcoming neutrino experiments will also be sensitive to physics beyond the Standard Model. KM3NeT/ORCA is a neutrino detector optimised for measuring atmospheric neutrinos from a few GeV to around 100 …
