Imprint of non-standard interactions on the CP violation measurements at long baseline experiments

Abstract

Neutrino oscillations have been firmly established in the past few decades due to a vast variety of experiments and five of the oscillation parameters (three angles and two mass-squared differences) have been measured to varying degrees of precision. Here the focus is on an important parameter entering the oscillation framework – the leptonic CP-violating phase $$\delta $$ , about which we know very little. We study the consequences of additional CP-conserving and CP-violating parameters in the presence of non-standard neutrino interactions (NSI) on CP-violation studies at the upcoming long baseline experiment, Deep Underground Neutrino Experiment (DUNE) and compare the capabilities of DUNE with other experiments.
