Connection between supernova shocks, flavor transformation, and the neutrino signal

Original · EN

We show that the supernova neutrino signal in terrestrial detectors could give characteristic signatures as the shock propagates through the regions where matter-enhanced neutrino flavor transformation takes place. This effect could allow existing and proposed supernova neutrino detectors to provide new insights into the problem of shock re-generation and propagation. Alternatively, such observations could allow unique insights into the neutrino mass and mixing matrix.
