CP-Violation and Non-Standard Interactions at the MOMENT

Abstract

To measure the last unknown $3\nu$ oscillation parameter ($\delta$), several long baseline neutrino experiments have been designed or proposed. Recently it has been shown that turning on neutral current Non-Standard Interactions (NSI) of neutrinos with matter can induce degeneracies that may even hinder the proposed state-of-the-art DUNE long baseline experiment from measuring the value of $\delta$. We study how the result of the proposed MOMENT experiment with a baseline of 150 km and $200\mathrm{MeV}<E_{\nu }<600\mathrm{MeV}$ can help to solve the degeneracy induced by NSI and determine the true value of $\delta$.
