Description

The The J-PARC Sterile Neutrino Search at the J-PARC Spallation Neutron Source (JSNS2) experiment has the unique ability to precisely measure monoenergetic 236 MeV neutrinos from charged kaon decay-at-rest (KDAR). J-PARC's Material and Life Science Facility (MLF) 3 GeV primary proton beam incident on a mercury target generates the world’s most intense source of KDAR which can be used to make neutrino cross-section measurements using known-energy neutrinos. In this poster, I will describe the analysis status for the KDAR neutrino measurement at JSNS2 using the first long-term physics run data set obtained during this year.
