Phys. Rev. D 59, 111901(R) (1999) [4 pages]Bound on the neutrino magnetic moment from chirality flip in supernovae
For neutrinos with a magnetic moment, we show that the collisions in a hot and dense plasma act as an efficient mechanism for the conversion of νL into νR. The production rate for right-handed neutrinos is computed in terms of a resummed photon propagator which consistently incorporates the background effects. Assuming that the entire energy in a supernova collapse is not carried away by the νR, our results can be used to place an upper limit on the neutrino magnetic moment μν<(0.1–0.4)×10-11μB. © 1999 The American Physical Society URL:
