Evaluation of the performance of the event reconstruction algorithms in the JSNS experiment using a Cf calibration source

D. H. Lee, M. K. Cheoun, J. H. Choi +50

JSNS searches for short baseline neutrino oscillations with a baseline of 24~meters and a target of 17~tonnes of the Gd-loaded liquid scintillator. The correct algorithm on the…
