Dynamics of Electron Neutrino inside Supernova and Bounds on Magnetic Moment of nu (sub E)

摘要

It is shown that if electron neutrino has magnetic moment mu approx. 10/sup -11/ mu /sub B/ then a resonant (i.e. complete) neutrino helicity flip is most likely to take place in the layer of supernova with density rho approx. 10/sup -12/ grams/cc. Therefore contrary to existing claims, such value of mu not only is consistent with neutrino events from the supernova SN1987A but can also explain mechanism for blowing off the supernova envelope. 16 refs.
