Supernova 1987a Did Not Test the Neutrino Mass Hierarchy Typeset Using Revt E X
We dispel the misconception that data from SN 1987A favor the normal neutrino mass hierarchy over the inverted hierarchy for sin 2 θ 13 > ∼ 10 −4. We find comparable fits for the two hierarchies. No bound can be placed on the mixing angle θ 13 even at the 1σ level.

متن کاملNeutrino oscillations and the supernova 1987A signal.
We study the impact of neutrino oscillations on the interpretation of the supernova (SN) 1987A neutrino signal by means of a maximum-likelihood analysis. We focus on oscillations between νe with νμ or ντ with those mixing parameters that would solve the solar neutrino problem. For the small-angle MSW solution (∆m2 ≈ 10−5 eV2, sin 2Θ0 ≈ 0.006), there are no significant oscillation effects on the...
متن کاملEffects of neutrino oscillation on supernova neutrino: inverted mass hierarchy
We study the effects of neutrino oscillation on supernova neutrino in the case of the inverted mass hierarchy (m3 ≪ m1 < m2) as well as the normal mass hierarchy (m1 < m2 ≪ m3). Numerical analysis using a realistic supernova and presupernova model allows us to discuss quantitatively a possibility to probe neutrino oscillation parameters. We show that information about the mass hierarchy can be ...
متن کاملDetecting the Neutrino Mass Hierarchy with a Supernova at IceCube
IceCube, a future km antarctic ice Cherenkov neutrino telescope, is highly sensitive to a galactic supernova (SN) neutrino burst. The Cherenkov light corresponding to the total energy deposited by the SN neutrinos in the ice can be measured relative to background fluctuations with a statistical precision much better than 1%. If the SN is viewed through the Earth, the matter effect on neutrino o...
