Description
We explore the scenario of Pseudo-Dirac neutrinos, where the mass degeneracy of Dirac neutrinos is lifted due to a soft breaking of the lepton number, resulting in 3 pairs of mass states which are maximally mixed.
Using prospects on the measurement of $pp$ and $^7$Be solar neutrinos in JUNO, we will demonstrate the capability of the experiment to explore the parameter space of including one of these extra finely split mass states, as well as the bounds it will be able to set on the full pseudo-Dirac scenario. We will show that JUNO will be able to put a 3$\sigma$ limit on the mass splitting being $\delta m^2$ $\lt$ 1.19 $\times$ 10$^{−13}$ eV$^2$ for a full Pseudo-Dirac scenario with identical mass splittings.
