Aiming at the calibration requirements of neutrino detectors, the single-photoelectron (SPE) responses of an MCP-PMT and a conventional dynode PMT are compared at the waveform level. By analyzing approximately 9 million digitized waveforms, we find that the MCP-PMT charge spectrum exhibits a pronounced high-charge tail. The fraction of events with charges above 3 p.e. is 0.66%, approximately...

The DUNE Near Detector Liquid Argon Detector (ND-LAr) is a modular, pixelated liquid argon time projection chamber designed to faithfully reconstruct neutrino interactions in a very intense beam environment. One of its prototypes, the 2×2 Demonstrator, collected 4.5 days of data in the NuMI antineutrino beam at Fermilab in 2024. We study the pixel-level detector response using the charge...

Massive stars emit neutrinos during their evolutionary phases, which can serve as an early warning of a nearby core-collapse supernova. However, current detectors are primarily sensitive mainly to silicon burning neutrinos, restricting the warning interval to only a few hours. In contrast, core oxygen burning persists for several months, but the associated neutrinos have lower energies and are...

In water Cherenkov detectors, particle direction is reflected in the spatial and temporal patterns of photomultiplier tube (PMT) signals. Individual PMT hits provide several low-level observables, such as hit position, charge, and timing, while additional directional information may also arise from correlations among these quantities. Understanding how such information is distributed across...

The SND@LHC experiment has been performed to detect high energy neutrinos produced in the forward direction at the LHC from 2022. This experiment can cover the unexplored ranges of energy (100 GeV-TeV) and pseudo-rapidity (7.2-8.4), in which a large fraction of neutrinos originate from charmed hadrons decays.

We investigate a class of baryogenesis scenarios in which the Standard Model is extended by heavy right-handed neutrinos (RHNs) and a scalar leptoquark. The out-of-equilibrium, CP-violating decays of the RHNs into quarks and leptoquarks generate a net $B-L$ asymmetry, which is subsequently converted into a baryon asymmetry through electroweak sphaleron processes. Unlike standard type-I seesaw...

Long-term stability of liquid scintillators (LSs) is essential for maintaining reliable detector performance in neutrino experiments.

We study resonant non-Abelian vector dark matter in an $SU(2)_X$ $\times U(1)_{Z'}$ gauge theory broken by a quintuplet dark Higgs field. The resulting gauge-boson mass spectrum naturally realizes a neutral mediator close to twice the dark matter mass, leading to velocity-dependent resonant annihilation in a WIMP-like scenario.
