Combined Effect of NSI and SFP on Solar Electron Neutrino Oscillation

الملخص EN

The combined effect of spin-flavor precession (SFP) and the nonstandard neutrino interaction (NSI) on the survival probability of solar electron neutrinos (assumed to be Dirac particles) is examined for various values of ϵ11, ϵ12, and μB.

It is found that the neutrino survival probability curves affected by SFP and NSI effects individually for some values of the parameters (ϵ11, ϵ12, and μB) get close to the standard MSW curve when both effects are combined.

Therefore, the combined effect of SFP and NSI needs to be taken into account when the solar electron neutrino data obtained by low energy solar neutrino experiments is investigated.
