Shock propagation and neutrino oscillation in supernova

Astrophysics 2009-11-07 v2

Abstract

The effect of the shock propagation on neutrino oscillation in supernova is studied paying attention to evolution of average energy of νe\nu_{e} and νˉe\bar{\nu}_{e}. We show that the effect appears as a decrease in average νe\nu_{e} (in case of inverted mass hierarchy, νˉe\bar{\nu}_{e}) energy at stellar surface as the shock propagates. It is found that the effect is significant 2 seconds after bounce if 3×105<sin2θ13<1023 \times 10^{-5} < \sin^{2}{\theta_{13}} < 10^{-2}.
