MicroBooNE is a $85$ tonne active mass liquid argon time projection chamber on the Booster Neutrino Beam at Fermi National Accelerator Laboratory. Studying neutral pion production in the MicroBooNE detector provides an opportunity to better understand neutrino-argon interactions, and is crucial for future accelerator-based neutrino oscillation experiments. This analysis presents the progress...
In the T2K experiment, new detectors are going to be installed to the near detector.
Super-FGD is one of them and a tracker which consists of 2 millions plastic scintillator cubes.
60 thousands wave length shifting fibers will be inserted to the cubes to lead scintillation light and it will be detected by SiPMs.
I will report the procedure to construct and install this detector.

The Telescope Array (TA) experiment, located near Delta, Utah, USA, is the largest ultra-high energy cosmic ray (UHECR) observatory in the northern hemisphere. When a UHECR primary particle arrives at the Earth, it collides with the atmosphere and produces a cascade of secondary particles known as an extensive air shower (EAS). The Telescope Array is designed to observe the EAS using a hybrid...
The Mu2e experiment at Fermilab will search for the charged-lepton flavor-violating process of a neutrino-less muon-to-electron decay in the presence of a nucleus. The experiment expects a single-event sensitivity of 2.9*10−17, which is four orders of magnitude below the current strongest limits on this process. This requires all backgrounds to sum to fewer than one event over the lifetime of...
An optical Time Projection Chamber (TPC) is proposed for future neutrino experiments. Its excellent particle detection momentum threshold, together with cost-effective scale-up prospects, make the TPC a strong candidate for reducing systematic errors due to neutrino-nucleus interactions.
In order to produce a high number of photons, the TPC is equipped with a thick gaseous electron multiplier...
The MicroBooNE detector is a liquid argon time projection chamber (LArTPC) with an 85 ton active mass that receives flux from the Booster Neutrino and the Neutrinos from the Main Injector (NuMI) beams, providing excellent spatial resolution of the reconstructed final state particles. Since 2015 MicroBooNE has accumulated many neutrino and anti-neutrino scattering events with argon nuclei...
The Mu2e Cosmic Ray Veto must veto cosmic-ray muons over a large area with an efficiency of 99.99% in the presence of high background rates. It consists of over 5000 scintillator extrusions with embedded wavelength-shifting fibers coupled to 2×2 mm2 silicon photomultipliers. A custom readout system consists of: (1) small circuit board, the Counter Mother Board, which provides a temperature...
The Mu2e experiment uses a cylindrical straw tube tracker operated in vacuum to provide a high precision momentum measurement of 105 MeV/c electrons that are the signal of charged lepton flavor violating (CLFV) muon to electron conversion. The tracker is instrumented with custom front-end electronics based on PolarFire FPGAs that sit at the outer radius of the tracker. Each straw is read out...
The JSNS2 experiment aims to search for the existence of sterile neutrino oscillations with deltam2 near 1eV2 at J-PARC MLF. A 1MW beam of 3 GeV protons incident on a spallation neutron target produces an intense neutrino beam from muon decay at rest. The experiment will search for muon antineutrino to electron antineutrino oscillations which can be detected by the inverse beta decay...
The constituents of dark matter are still unknown, and the viable possibilities span a very large mass range. The scenario where dark matter originates from thermal contact with familiar matter in the early Universe requires the DM mass to lie within about an MeV to 100 TeV. Considerable experimental attention has been given to exploring Weakly Interacting Massive Particles in the upper end of...
The MicroBooNE liquid argon time projection chamber (LArTPC) experiment is pursuing a broad range of neutrino physics measurements, including some of the first high-statistics results for neutrino-argon scattering cross sections. At the neutrino energies relevant for MicroBooNE and its companion experiments in the Fermilab Short-Baseline Neutrino program, the dominant event topology involves...
