| contents | 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 $π_0$ 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 $δ_{13}$ and unknown CP phase $δ_{14}$ are explored at the firm footing. Slight deteriorations are observed in CP violations induced by $δ_{13}$ as the presence of sterile neutrino is considered. We also look at the reconstruction of CP violations phases $δ_{13}$ and $δ_{14}$ and the MOMENT experiment shows significant capabilities in the precise measurement of $δ_{13}$ phase. |
