Our goal is to identify the tau neutrino charged current events in DUNE's liquid argon time projection chamber (LArTPC) far detectors. To identify...
Newly designed photodetectors with a large 50-cm aperture were developed for future neutrino experiments. About twenty thousand R12860 photomultiplier tubes (PMTs) with a box-and-line dynode, manufactured by Hamamatsu Photonics, were selected for the next-generation water Cherenkov detector, Hyper-Kamiokande. Operation is scheduled to begin in 2028 with the world’s largest 260k metric tons of...
The PIKACHU experiment is a search for the double beta decay of 160Gd using large single crystals of Ce:Gd3Al2Ga3O12 (GAGG). In particular, it aims to observe the so-far undetected two-neutrino double beta decay (2nbb) of 160Gd down to half-lives predicted by theory. We have been developing high-purity GAGG crystals, and in 2023, succeeded in producing crystals with uranium- and thorium-series...
The LEGEND collaboration aims to unambiguously discover neutrinoless double-beta decay (0νββ) using high-purity germanium (HPGe) detectors enriched in the double-beta-decaying isotope $^{76}$Ge (Q$_{ββ}$ = 2039 keV). The HPGe detectors operate in liquid argon, which serves as a coolant and an active shield, enabling a quasi background-free search for 0νββ decay. The first phase, LEGEND-200,...
Non-standard interactions (NSI) are a compelling beyond-the-Standard-Model (BSM) framework for explaining the tensions between the T2K experiment and the $\operatorname{NO\nu A}$ experiment results. They can be formulated as general neutrino– or antineutrino–flavour-changing scattering processes with fermions in matter. In oscillation phenomenology, NSI enter as additional matter-potential...

SuperNEMO is a double-beta-decay experiment, whose isotope-agnostic tracker-calorimeter architecture has the unique ability to track trajectories and energies of individual particles. If the hypothesised lepton-number-violating process, neutrinoless double-beta decay (0νββ), is discovered, this full topological event reconstruction will be the only way to determine the mechanism. The detector...
The LEGEND collaboration aims to uncover the fundamental nature of neutrinos, specifically whether they are Majorana particles, by searching for neutrinoless double-beta ($0\nu\beta\beta$) decay in $^{76}$Ge (Q$_{\beta\beta}$ = 2039 keV).
