New Supernova Constraints on Sterile-Neutrino Production.
We consider the possibility that a light, sterile-neutrino species νS can be produced by νe scattering during the cooling of a proto-neutron star. If we parameterize the sterile-neutrino production cross section by a parameter A as σ(νeX −→ νSX) = Aσ(νeX −→ νeX), where X is an electron, neutron, or proton, we show that A is constrained by limits to the conversion of νe to νS in the region betwe...
متن کاملSupernova constraints on neutrino mass and mixing
In this article I review the constraints on neutrino mass and mixing coming from type-II supernovae. The bounds obtained on these parameters from shock reheating, r-process nucleosynthesis and from SN1987A are discussed. Given the current constraints on neutrino mass and mixing the effect of oscillations of neutrinos from a nearby supernova explosion in future detectors will also be discussed.
متن کاملSupernova Bounds on Resonant Active-Sterile Neutrino Conversions
We discuss the effects of resonant νe → νs and ν̄e → ν̄s (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 ν̄e signal from SN1987A and for the r-process nucleosynthesis hypothesis are analysed ...
متن کاملNeutrino mixing constraints and supernova nucleosynthesis.
We reexamine the constraints on mixing between electron and muon or tau neutrinos from shock-reheating and r-process nucleosynthesis in supernovae. To this end neutrino flavor evolution is described by nonlinear equations following from a quantum kinetic approach. This takes into account neutrino forward scattering off the neutrino background itself. In contrast to other claims in the literatur...
متن کاملDirect X-ray Constraints on Sterile Neutrino Warm Dark Matter
Warm dark matter (WDM) might more easily account for small scale clustering measurements than the heavier particles typically invoked in Λ cold dark matter (ΛCDM) cosmologies. In this paper, we consider a ΛWDM cosmology in which sterile neutrinos νs, with a mass ms of roughly 1-100 keV, are the dark matter. We use the diffuse X-ray spectrum (total minus resolved point source emission) of the An...
