The fact that neutrinos have a nonzero rest mass would provide clear evidence of physics beyond the Standard Model, with wide-reaching implications in both particle physics and cosmology. The KATRIN (Karlsruhe Tritium Neutrino) experiment aims to determine the absolute neutrino mass scale by performing high-precision spectroscopy of electrons emitted in tritium beta decay near the kinematic...
NOvA represents the second generation of accelerator-based long-baseline neutrino experiments conducted at Fermilab. Utilizing the megawatt-capable NuMI beam, neutrinos or antineutrinos are produced to study oscillation phenomena across an 810 km baseline. Two functionally identical and finely segmented tracking detectors filled with liquid scintillator have been collecting data for the past...
Since beginning operations in 1996, Super-Kamiokande has played a pivotal role in advancing our understanding of neutrino mixing, solar and supernova astrophysics, and in setting some of the most stringent limits on nucleon decay. These efforts have been further strengthened by the recent phased addition of gadolinium to the detector’s pure water volume, significantly improving antineutrino...
The ICARUS Collaboration is now entering its fifth year of continuing operations of the 760-ton liquid argon T600 detector. The T600 was overhauled at CERN after operations at the LNGS underground laboratory in Italy and moved to its present location at FNAL - as part of the Short-Baseline Neutrino (SBN) program - where it successfully completed its commissioning phase in June 2022. At FNAL...
The KM3NeT neutrino telescope is a next-generation research infrastructure currently under construction in the Mediterranean Sea. It aims to address fundamental questions in neutrino and astroparticle physics. The facility consists of two deep-sea detectors: ARCA (Astroparticle Research with Cosmics in the Abyss) and ORCA (Oscillation Research with Cosmics in the Abyss). ARCA is located...
Neutrinoless double-beta decay (0νββ) provides an exciting avenue for probing the absolute neutrino mass and the Majorana nature of the neutrino. Regardless of the mechanism involved in its production, the observation of 0νββ implies new physics, exhibiting lepton number violation, and providing insight into the matter-antimatter asymmetry in the universe. Ge detector technology is extremely...
The scotogenic model is a minimally extended model that generates small neutrino masses through radiative corrections in the dark sector. It is also known to account for the baryon asymmetry of the Universe through the decay of right-handed neutrinos. In this work, we explored an alternative leptogenesis scenario in which the scalar doublet decays into a right-handed neutrino and a lepton...
