The relatively large value of the neutrino mixing angle θ 13 set by recent measurements allows us to use solar neutrinos to set a limit on the neutrino magnetic moment involving the second and third flavor families, μ 23 . The existence of a random magnetic field in the solar convective zone can produce a significant antineutrino flux when a nonvanishing neutrino magnetic moment is assumed. Even if we consider a vanishing neutrino magnetic moment involving the first family, electron antineutrinos are indirectly produced through the mixing between the first and third families and μ 23 ≠ 0. Using KamLAND limits on the solar flux of electron antineutrino, we set the limit μ 23 < 0.95 × 10 −11 μ B as a reasonable assumption on the behavior of solar magnetic fields. This is the first time that a limit on μ 23 has been established in the literature directly from neutrino interactions with magnetic fields, and, interestingly enough, is comparable with the limits on the neutrino magnetic moment involving the first family and with the ones coming from modifications to the electroweak cross section.

New limits on the weak mixing angle and on the electron neutrino effective charge radius in the low energy regime, below 100 MeV, are obtained from a combined fit of all electron-(anti)neutrino electron elastic scattering measurements. We have included the recent TEXONO measurement with a CsI (Tl) detector. Only statistical error of this measurement has been taken into account. Weak mixing angle is found to be sin 2 θW = 0.255 +0.022 −0.023 . The electron neutrino effective charge radius squared is bounded to be r 2 νe = (0.9 +0.9 −1.0 ) × 10 −32 cm 2 . The sensitivity of future low energy neutrino experiments to nonstandard interactions of neutrinos with quarks is also discussed.

“…[The literature on neutrino magnetic moments is extensive. For some recent works see [11,12,13] and for recent reviews see [14,15,16]]. In any case one finds that all of the limits above whether experimental or theory are several orders of magnitude larger than the estimate of Eq.…”
