abstract

We study several methods for timing the neutrino signal of a Galactic supernova (SN) for different detectors via Monte Carlo simulations. We find that, for the methods we studied, at a distance of $10\,$kpc both Hyper-Kamiokande and IceCube can reach precisions of $\sim1\,$ms for the neutrino burst, while a potential IceCube Gen2 upgrade will reach submillisecond precision. In the case of a failed SN, we find that detectors such as SK and JUNO can reach precisions of $\sim0.1\,$ms while HK could potentially reach a resolution of $\sim 0.01\,$ms so that the impact of the black hole formation process itself becomes relevant. Two possible applications for this are the triangulation of a (failed) SN as well as the possibility to constrain neutrino masses via a time-of-flight measurement using a potential gravitational wave signal as reference.

  1. Neutrino Constraints on Scalar-Tensor Gravity

    hep-ph 2025-12 conditional novelty 6.0 of 10

    Spatially varying scalar fields rescale neutrino masses and arrival times, and neutrino data bound these rescaling parameters for Symmetron and Chameleon models.

    hep-ph 2025-11 conditional novelty 6.0 of 10

    Binary neutron star merger neutrinos will require a megaton-scale detector and decades of operation to detect, but a single detected neutrino could set a sub-eV (~0.1 eV) limit on the lightest neutrino mass via gravit...

    hep-ph 2024-11 conditional novelty 6.0 of 10

    Using time-of-flight delays of the three neutrino mass eigenstates across sharp supernova features, a galactic supernova at 10 kpc could individually constrain or measure neutrino masses at JUNO, with precision that d...
