Spectral split in a prompt supernova neutrino burst: Analytic three-flavor treatment
Spectral split in a prompt supernova neutrino burst: Analytic three-flavor treatment
The prompt ${\ensuremath{\nu}}_{e}$ burst from a core-collapse supernova is subject to both matter-induced flavor conversions and strong neutrino-neutrino refractive effects. For the lowest-mass progenitors, leading to O-Ne-Mg core supernovae, the matter density profile can be so steep that the usual Mikheyev-Smirnov-Wolfenstein matter effects occur within the dense-neutrino region close to …
