Supernova observations for neutrino mixing parameters

The neutrino spectra from a future galactic core collapse supernova could reveal information on the neutrino mixing pattern, especially on θ13 and the mass hierarchy. I briefly outline our current understanding of neutrino flavor conversions inside a supernova, and point out possible signatures of various neutrino mixing scenarios that the neutrino detectors should look for. Supernova neutrinos provide a probe for θ13 and mass hierarchy that is complementary to, and sometimes even better than, the current and proposed terrestrial neutrino oscillation experiments.
