The J-PARC muon g-2/EDM experiment aims to measure the muon magnetic moment anomaly (a_μ = (g-2)/2) and to search for the muon electric dipole moment, with sensitivity comparable to the highest in the world. This will be achieved using a small-emittance muon beam, created by cooling muons and accelerating them with a multi-stage linac. The experimental approach significantly differs from the...
The currently operating T2K long baseline neutrino experiment is probing the phenomenon of neutrino oscillations, providing world leading constraints on neutrino mixing parameters while searching for CP violation in neutrinos. The next generation experiment, Hyper-Kamiokande (Hyper-K), is currently under construction and will succeed T2K and Super-Kamiokande with a higher beam intensity and...
We are advancing the NINJA experiment at J-PARC using nuclear emulsion to study low-energy neutrinos in the Sub-Multi GeV range. Currently, we are conducting a physics run aimed at the precise measurement of neutrino-water interactions, which is crucial for reducing systematic uncertainties in long-baseline neutrino oscillation experiments that test CP symmetry violation in the lepton sector....
Tau neutrinos is one of least studied particles. Measurement of the interaction crossection with a nucleon were reported by DONuT experiment but larger statistical and systematic errors. SHiP experiment is a hybrid experimnt constructing and run in 2030s. The experiment have two main subjevts, one is hidden particle search in a large decay volume and the other is tau neutrino detector with...
Super-Kamiokande (SK) has been operational since 1996, revealing neutrino oscillations and precisely measuring oscillation parameters. With the extensive atmospheric neutrino data collected, we have recently been exploring the neutrino mass hierarchy. In 2020, gadolinium was added to the SK tank, and since then, we have been collecting data with neutron tagging information. One of the most...
