New sources of leptonic CP violation at the DUNE neutrino experiment

TL;DR

This paper evaluates DUNE's potential to discover new leptonic CP violation sources beyond the Standard Model, focusing on non-standard neutrino interactions and sterile neutrinos, especially via the  transition.

Contribution

It introduces a strategy to detect new leptonic CP violation sources at DUNE, emphasizing the  transition and considering non-standard interactions and sterile neutrinos.

Findings

The  transition is the most promising channel for detecting new CP violation.

DUNE can potentially identify new CP violation sources despite experimental errors.

Non-standard neutrino interactions and sterile neutrinos can produce observable CP asymmetries.

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 $\nu_\mu \to \nu_e$ transition.
