Search of Sterile Neutrino in MicrobooNE
Yaozheng Shen · 2023
MicrobooNE is a liquid argon Time Projection Chamber(TPC) used for studying neutrino oscillations.It is currently contributing data to the Deep Underground Experiment and it is providing important data to help us find the sterile neutrino, which can help to explain the low energy excess phenomena.After a search for the eV-scale sterile neutrino oscillations in the liquid argon detector, it shows no evidence that the sterile neutrino really exists.The exclusion limits have also been calculated and it comes up with a frequentist CLs exclusion contour with 95% confidence level.
