Description
The coupling of neutrinos with complex scalar dark matter particles can have interesting phenomenological signatures in neutrino oscillation experiments. For time-averaged data, it appears as an energy-dependent correction to the mass-squared term in the neutrino Hamiltonian. We study the effect of neutrino scattering with scalar dark matter termed dark Non-Standard Interaction (dark NSI) in the context of the long baseline experiment DUNE. The phases associated with the off-diagonal elements of the dark NSI matrix can act as additional sources of CP violation apart from the genuine Dirac CP phase, hampering the measurement of $\delta_{CP}$. We will present the phenomenological consequences of dark NSI in neutrino oscillation and its effect on the CP violation sensitivity of DUNE.
