dc.description.abstractWe study the consequences on the neutrino oscillation parameter space, mixing angle (tan2θ), and vacuum mass difference (Δm02) when mass varying neutrino (MaVaN) models are assumed in a supernova environment. We consider electronic to sterile channels ν e→νs and ν̄e→ν ̄s in two-flavor scenario. In a given model of MaVaN mechanism, we induce a position-dependent effective mass difference, Δm2(r), where r is the distance from the supernova core, that changes the neutrino and antineutrino flavor conversion probabilities. We study the constraints on the mixing angle and vacuum mass difference coming from r-process and the SN1987A data. Our result is the appearance of a new exclusion region for very small mixing angles, tan2θ=10-6-10-2, and small vacuum mass difference, Δm02=1-20eV2, due the MaVaN mechanism. © 2011 American Physical Society.en
