Spectral swaps in a two-dimensional neutrino ring model
Spectral swaps in a two-dimensional neutrino ring model
Neutrinos emitted deep within a supernova explosion experience a self-induced index of refraction. In the stationary, one-dimensional (1D) supernova ``bulb model,'' this self-induced refraction can lead to a collective flavor transformation which is coherent among different neutrino momentum modes. Such collective oscillations can produce partial swaps of the energy spectra …
