Supernova neutrino oscillations: adiabaticity improvement by Majoron fields
نویسنده
چکیده
If the lepton numbers are associated to global symmetries spontaneously broken at a scale below 1 TeV, neutrino oscillations in Supernovae produce classic Majoron fields that perturb the neutrino propagation itself and may change the oscillation patterns in the periods of largest ν fluxes. The impact of the Majoron fields on the same transitions as νe → νX that presumably occur in the Sun is studied in the case of the non-adiabatic MSW solution. It is shown how the back reaction of the Majoron fields may improve the adiabaticity of these oscillations in a Supernova environment which has implications on the outgoing νe spectrum.

Non-adiabatic oscillations of supernova neutrinos
The level-crossing probability, local and global adiabaticity conditions are discussed for 2-flavour neutrino oscillations in matter with arbitrary mixing angles θ. Different approximations for the survival probability of supernova neutrinos are compared. Results of a combined likelihood analysis of the observed SN 1987A neutrino signal and of the latest solar neutrino data including the recent...

It is shown that a true Nambu-Goldstone (NG) boson develops a coherent long-range field whenever the charge associated with it that is carried by the other particles is not conserved in a macroscopic scale. The source of a NG field is the time rate of quantum number violation. If the lepton numbers are spontaneously broken at a scale below 1 TeV, the neutrino oscillation processes generate long...
متن کاملDecays of Supernova Relic Neutrinos
We propose that future observation of supernova relic neutrino (SRN) can be used to probe neutrino decay models. We focus on invisible (e.g., Majoron) decays, and work out the general solution of SRN kinetic equations in the presence of oscillations plus decay. We then apply the general solution to specific decay scenario, and show that the predicted SRN event rate can span the whole range belo...
متن کاملDecays of supernova neutrinos
Supernova neutrinos could be well-suited for probing neutrino decay, since decay may be observed even for very small decay rates or coupling constants. We will use a combined description of neutrino decay and neutrino oscillations for supernova neutrinos, especially taking into account two properties: One is the radially symmetric neutrino flux, allowing a decay product to be re-directed toward...
متن کاملNeutrino signatures of supernova forward and reverse shock propagation
A few seconds after bounce in a core-collapse supernova, the shock wave passes the density region corresponding to resonant neutrino oscillations with the " atmospheric " neutrino mass difference. The transient violation of the adiabaticity condition manifests itself in an observable modulation of the neutrino signal from a future galactic supernova. In addition to the shock wave propagation ef...
