Supernova neutrino spectrum with matter and spin flavour precession effects

We consider Majorana neutrino conversions inside supernovae by taking into account both flavour mixing and the neutrino magnetic moment. We study the adiabaticity of various possible transitions between the neutrino states for both normal and inverted hierarchy within the various solar neutrino problem solutions. From the final mass spectrum within different scenarios, we infer the consequences of the various conversion effects on the neutronization peak, the nature of final spectra, and the possible Earth matter effect on the final fluxes. This enables us to check the sensitivity of the SN neutrino flux on magnetic moment interaction, and narrow down possible scenarios which depend on the normal or inverted mass spectrum, the solution of the solar neutrino problem and the value of muB.
