New sources of leptonic CP violation at the DUNE neutrino experiment

Abstract

We check the capability of the DUNE neutrino experiment to detect new sources of leptonic CP violation beside the single phase expected in the Standard Model. We illustrate our strategy based on the measurement of CP asymmetries in the case New Physics will show up as Non-Standard neutrino Interactions and sterile neutrino states and show that the most promising one, once the experimental errors are taken into account in both scenarios, is the one related to the $\hat{I}{½}_{\hat{I}}¼\to \hat{I}{½}_e$ transition.
