Supernova 1987A did not test the neutrino mass hierarchy
V. Barger, D. Marfatia, B. P. Wood
Abstract
We dispel the misconception that data from SN 1987A favor the normal neutrino mass hierarchy over the inverted hierarchy for 2 θ13 10-4. We find comparable fits for the two hierarchies. No bound can be placed on the mixing angle θ13 even at the 1σ level.
