| dc.description.abstract | We discuss the effects of resonant νe→νs and ν¯e→ν¯s (νs is a sterile neutrino) conversions in the dense medium of a supernova. In particular, we assume the sterile neutrino νs to be in the hot dark matter few eV mass range. The implications of such a scenario for the supernova shock re-heating, the detected ν¯e signal from SN1987A and for the r-process nucleosynthesis hypothesis are analysed in some detail. The resulting constraints on mixing and mass difference for the νe−νs system are derived. There is also an allowed region in the neutrino parameter space for which the r-process nucleosynthesis can be enhanced. | |
