Description
The JSNS2 (J-PARC Sterile Neutrino Search at the J-PARC Spallation Neutron Source) is an experiment with a neutrino detector utilizing a 3GeV proton beam on a mercury target in the J-PARC Materials and Life Science Experimental Facility. The primary goal of the JSNS2 experiment is to search for the sterile neutrino with Δm2 ~ 1eV by measuring a neutrino oscillation at a short baseline of 24m, providing a direct test of the LSND anomalies. The JSNS2 experiment started commissioning in 2020 and continued physics data collection in 2023. A new far detector for JSNS2-II, which is the 2nd phase of the experiment using two detector is under construction at a distance of 48m from the source to increase the sensitivity of the sterile neutrino search. In this talk, we summarize the recent status of JSNS2 and JSNS2-II.
