초록

JSNS(2) (J-PARC Sterile Neutrino Search at J-PARC Spallation Neutron Source) is an experiment that is searching for sterile neutrinos via the observation of (v) over bar (mu) -> (v) over bar (e) appearance oscillations using muon decay-at-rest neutrinos. Before dedicated data taking in the first-half of 2021, we performed a commissioning run for 10 days in June 2020. Using the data obtained in this commissioning run, in this paper, we present an estimate of the correlated background which imitates the (v) over bar (e) signal in a sterile neutrino search. In addition, in order to demonstrate future prospects of the JSNS(2) experiment, possible pulse shape discrimination improvements towards reducing cosmic ray induced fast neutron background are described.
