Covering All the Bases: Searching for Pseudo-Dirac Neutrinos in the Atmospheric Regime
Abstract: To date, most studies into the possible Pseudo-Dirac nature of neutrinos have primarily been focused on the cosmic scale due to the requirements of an extremely long baseline to observe such effects. However, potential avenues still exist at 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 parameter space 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 highlight and discuss what sensitivity, if at all, could DUNE have to the Pseudo-Dirac neutrino hypothesis in the case of a single new mass squared splitting.
