The Width of an Electron-Capture Neutrino Wave Packet

B. J. P. Jones, E Marzec, J. Spitz

We discuss the size of an electron neutrino wave packet emerging from an electron capture decay using the formalism of open quantum systems. This quantitative result is based on me…

Measurement of reactor antineutrino oscillation at SNO+

SNO+ Collaboration, :, M. Abreu +298

The SNO+ collaboration reports its second spectral analysis of reactor antineutrino oscillation using 286 tonne-years of new data. The measured energies of reactor antineutrino can…

PMT calibration for the JSNS2-II far detector with an embedded LED system

Jisu Park, M. K. Cheoun, J. H. Choi +53

The JSNS2-II (the second phase of JSNS2, J-PARC Sterile Neutrino Search at J-PARC Spallation Neutron Source) is an experiment aimed at searching for sterile neutrinos. This experim…

First Measurement of Missing Energy Due to Nuclear Effects in Monoenergetic Neutrino Charged Current Interactions

E. Marzec, S. Ajimura, A. Antonakis +80

We present the first measurement of the missing energy due to nuclear effects in monoenergetic, muon neutrino charged-current interactions on carbon, originating from $K^+ \rightar…

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…
