Constraining neutrino mass using black hole formation during supernova neutrino emission — •George Parker and Michael Wurm — Johannes Gutenberg Universität Mainz, Mainz, Germany

In this work, we study how neutrino emission from supernovae collapsing to black holes could be used constrain the absolute neutrino mass. In the case where a black hole forms during a core-collapse supernova, it would lead to a sharp cut-off in the neutrino flux. An abrupt drop-off in the neutrino emission offers a clear-cut stage to look for neutrino time-of-flight effects, allowing stricter constraints to be set on the neutrino mass compared to previous estimates. We focus on the possibility that supernova neutrinos are detected with the Jiangmen Underground Neutrino Experiment (JUNO), a next-generation neutrino experiment with enhanced flavour sensitivity, exceptional energy resolution and high statistics. Using three-dimensional core-collapse supernova simulations, the sensitivity of JUNO to the absolute neutrino mass is evaluated.
