Testing Pseudo-Dirac Sensitivity with Atmospheric Neutrino Studies

While many studies into the Pseudo-Dirac nature of neutrinos have primarily been focused on the cosmic scale due to the requirements of an extremely long baseline, potential avenues still exist on the terrestrial level. In particular, atmospheric neutrino studies, such as those already being planned as the initial studies for the upcoming DUNE experiment, could potentially probe this scenario due in large part to the relatively long baseline distances of up to approximately the Earth’s diameter that such studies can provide. Therefore, motivated by the fact that DUNE will be coming online in the near term (early 2030s), this talk will seek to discuss what sensitivity, if at all, could DUNE (and possibly other next generation neutrino experiments) have to the Pseudo-Dirac neutrino hypothesis in the case of a single new mass splitting.
