Implications of a fine structure in the reactor neutrino spectrum for JUNO — David Blum, Marc Breisch, Jessica Eck, •Tobias Heinz, Tobias Lachenmaier, Neha Lad, Axel Müller, Tobias Sterr, and Alexander Tietzsch — Physikalisches Institut, Eberhard Karls Universität Tübingen

With the main goal to determine the neutrino mass hierarchy, the Jiangmen Underground Neutrino Observatory (JUNO) is currently constructed in the Guangdong province in southern China. To analyze which mass hierarchy is realized in nature, JUNO measures the reactor neutrino spectrum from two nuclear power plants located in a distance of around 53 km. One crucial aspect for a successful measurement is a precise knowledge of the emitted and therefore unoscillated reactor neutrino spectrum. In the last years, new predictions of the spectrum revealed the possible existence of a spectral fine structure which could impede the mass hierarchy determination with JUNO.

This work will present studies on possible implications of the fine structure in the reactor neutrino spectrum for the sensitivity of the mass hierarchy determination with JUNO.
