Resonant spin flavor precession solution to the solar neutrino problem and electron anti-neutrinos from the sun

We have found allowed ∆m, μB⊥, sin 2 2θ – regions for the Resonant SpinFlavor Precession Solution (RSFP) [1] to the Solar Neutrino Problem (SNP) fitted with data of all acting solar neutrino experiments. The tipical mass difference region ∆m ∼ 5·10−2·10 eV varying in dependence on the mixing 0 ≤ sin 2θ ∼ 8.3 MeV [3]). This limit occurs also sensitive to the magnetic field parameter μB⊥. While at 67% CL (±σ) there is another more stringent upper limit s22 ≤ s22max1 ∼ 0.05 coming from inconsistency of gallium experiments with others that is also close to the result s2 <∼ 0.25 [4]. A new allowed region (∆m ≈ 10eV, sin 2θ ≈ 0.01) appears in the case of additional assumption that the Homestake data are 1.3 times less than the experimental event rate.
