MicroBooNE is a Liquid Argon Time Projection Chamber detector that has been taking data since 2015. One of its primary goals is to investigate the unexplained excess of electromagnetic events in the lowest energy ranges observed by the MiniBooNE experiment located along the same neutrino beamline. While one leading interpretation of this anomaly is electron neutrino appearance due to sterile...

The liquid argon time projection chamber (LArTPC) is an advanced technology to detect neutrinos with its superb imaging and calorimetry capabilities in a fully active volume. The MicroBooNE detector, which is a single-phase LArTPC of 85-ton active mass located near the Earth's surface, was built to primarily investigate the low energy excess (LEE) of electron neutrino charged-current events...

MicroBooNE is an 85-ton active mass liquid argon time projection chamber (LArTPC) at Fermilab. Its excellent calorimetry and resolution, along with its exposure to two neutrino beamlines make it a powerful detector not just for neutrino physics, but also for Beyond the Standard Model (BSM) physics and astrophysics. The experiment has competitive sensitivity to Heavy Neutral Leptons arising in...

We present results of searches for light sterile neutrino oscillations at RENO. We have conducted a sub-ev scale sterile neutrino oscillation search using the RENO far and near detector data and an eV scale sterile neutrino oscillation search combining the RENO and NEOS data. The identical RENO near and far detectors are located at 294 m (near) and 1383 m (far), respectively, from the center...

The existence of massive or massless weakly interacting neutral particles $X$ such as axion-like particles, sterile neutrinos, and Majorons has been suggested to augment the standard model with motivations that include providing dark matter candidates, explaining baryogenesis, and revealing the origin of neutrino masses. The three body pion decays ${\pi}^+{\to}l^+{\nu}X(l=e,{\mu})$ involving...

The JSNS2 (J-PARC Sterile Neutrino Search at the J-PARC Spallation Neutron Source) experiment will search for neutrino oscillations over a short 24 m baseline with delta m square near 1 eV square at the J-PARC Materials and Life Science Experimental Facility. The JSNS2 detector is filled with 17 tons of gadolinium-loaded liquid scintillator (LS) with an additional 31 tons of unloaded LS in...

The detailed analysis of the results of the Neutrino-4 experiment obtained from the beginning of the experiment in 2016 to the present is presented. The analysis was carried out on all statistical material. The main task of the analysis performed is to identify possible systematic errors of the experiment. The result of analysis will be presented.

What if the dark matter content of the universe was made up of sterile neutrinos with a mass of the order of keV?

Currently, constraints from the measured relic abundance of dark matter and from observations in the X-ray band threaten the possibility of finding in terrestrial experiments a signal of such sterile neutrinos produced through oscillation and collisions in the early universe.... -

The purpose of the JSNS2 experiment is to search for sterile neutrinos with Δm2 near 1eV2. A 3 GeV J-PARC proton beam incident on a mercury target produces an intense neutrino beam from muon decay at rest which oscillates to anti-electron neutrinos. The JSNS2 detector is located at 24 m baseline from the target. The detector has a fiducial volume of 17 tons filled with GdLS, that efficiently...

Liquid Argon Time Projection Chambers (LArTPCs) are an important technology in the field of experimental neutrino physics due to their exceptional calorimetric and position resolution capabilities. In particular, their ability to distinguish electrons from photons is crucial for current and future neutrino oscillation experiments. The MicroBooNE experiment is utilizing LArTPC technology to...

The J-PARC Sterile Neutrino Search at the J-PARC Spallation Neutron Source (JSNS2) experiment has started the search for neutrino oscillations with ∆m2 ~ 1 eV2 from anti-muon neutrino to Anti-electron neutron detected via the inverse beta decay (IBD) reaction which is tagged via gammas from neutron capture on Gadolinium. A 3 GeV 1 MW proton beam incident on a mercury target at the MLF at...
