| Abstract: | We analyze the influence of neutrino helicity conversion, ν
L → ν
R, on the neutrino flux from a supernova attributable to the interaction of the Dirac neutrino magnetic moment with a magnetic
field.We show that if the neutrino has a magnetic moment in the interval 10−13μB < μν < 10−12μB and provided that a magnetic field of ∼1013–1014 G exists in the supernova envelope, a peculiar kind of time evolution of the neutrino signal from the supernova attributable
to the resonance transition ν
L → ν
R in the magnetic field of the envelope can appear. |
