The ANTARES neutrino telescope was operational in the Mediterranean Sea from 2006 to 2022. The detector array, consisting of 12 lines with a total of 885 optical modules, was designed to detect high-energy neutrinos covering energies from a few tens of GeV up to the PeV range. Despite the relatively small size of the detector, the results obtained are relevant in the field of neutrino physics...
The IceCube Neutrino Observatory, together with its DeepCore sub-array, detects large amounts of atmospheric neutrinos in the GeV to TeV energy range, enabling measurements of the muon-neutrino disappearance and tau-neutrino appearance channels of neutrino oscillations over a wide range of baselines up to 12000 km. In the energy range of DeepCore between 5 GeV and 150 GeV in particular, these...
The hunt for neutrinos from Gamma-Ray Bursts (GRBs) could also be significant in quantum-gravity research, since they are ideal probes of the microscopic fabric of spacetime. One of the most studied candidate effects of quantum gravity is in-vacuo dispersion, an energy-dependent correction to the speed of ultrarelativistic particles, and in a recent studywe investigated the hypothesis that...
Neutrinoless double-beta decay is a nuclear decay, given as (A,Z) --> (A,Z+2)+2e-, that violates total lepton number conservation by two units. Its observation would have deep consequences in the understanding of our Universe. It would prove that neutrinos have a Majorana component, it would help to understand the origin of the neutrino mass and constrain its absolute mass and help to...
Neutrinoless double beta decay ($0\nu\beta\beta$) is a hypothetical nuclear process which, if observed, would have far-reaching implications in particle physics. Being a lepton number violating process, the observation of $0\nu\beta\beta$ is direct evidence for physics beyond the Standard Model. In addition, it would prove that neutrinos are Majorana particles, and contribute to the...
Neutrinoless double-beta decay (0νββ) is a key process to address some of the major outstanding issues in particle physics, such as the lepton number conservation and the Majorana nature of the neutrino. Several efforts have taken place in the last decades in order to reach higher and higher sensitivity on its half-life. The next-generation of experiments aims at covering the Inverted-Ordering...
