Testing generalized CP symmetries with precision studies at DUNE

Abstract

We examine the capabilities of the DUNE experiment in probing leptonic CP violation within the framework of theories with generalized CP symmetries characterized by the texture zeros of the corresponding CP transformation matrices. We investigate DUNE's potential to probe the two least known oscillation parameters, the atmospheric mixing angle ${\theta }_{23}$ and the Dirac CP-phase ${\delta }_{\mathrm{CP}}$. We fix theory-motivated benchmarks for (${\sin }^2{\theta }_{23},{\delta }_{\mathrm{CP}}$) and take them as true values in our simulations. Assuming 3.5 years of neutrino running plus 3.5 years in the antineutrino mode, we show that in all cases DUNE can significantly constrain and in certain cases rule out the generalized CP texture zero patterns.
