Impact of CP violation searches at MOMENT experiment with sterile neutrino

Abstract

Abstract We examine the scope of the MOMENT experiment in the context of CP violation searches with the presence of extra eV scale sterile neutrino. MOMENT is a proposed medium baseline neutrino oscillation experiment using muon beams for neutrinos production, making it advantageous over π0 background and other technical difficulties. We work over the first oscillation maxima which matches the peak value of flux with a run time of 5 years for both neutrino and anti-neutrino modes. We perform the bi-probability studies for both 3 and 3+1 flavor mixing schemes. The CP violation sensitivities arising from the fundamental CP phase δ13 and unknown CP phase δ14 are explored at the firm footing. Slight deteriorations are observed in CP violations induced by δ13 as the presence of sterile neutrino is considered. We also look at the reconstruction of CP violations phases δ13 and δ14 and the MOMENT experiment shows significant capabilities in the precise measurement of δ13 phase.
