Question

How to calculate the energy of neutrinos from a supernovae

Answer 1

Answer:

The anisotropy of the positrons emitted in the reaction ν e+ p→ n+ e+ has to be taken into account for extracting an antineutrino signal in Superkamiokande. For the Sun, this effect allows a sensitivity to ν e→ ν e transition probability at the 3% level already with the statistics
