“…This paper is a continuation of the works [12,13,14] in which the correlation between the SF's and behavior of the neutrino beam was discussed. It is clear that when the electron neutrinos beam passing through the magnetic field of the CS's will change its composition and we could detect this changing, then the problem of the SF's forecasting with a help of neutrino telescopes will be resolved.…”

The behavior of the neutrino flux in vortex and twisting magnetic fields is considered within the left-right symmetric model. By way of illustration of the magnetic fields we discuss the magnetic fields of the coupled sunspots (CS's) which are the sources of the future solar flares. It is expected that the neutrinos have such multipole moments as the charge radius, the magnetic and anapole moments. The evolution equation in the Schrodinger-like form is found and all magnetic-induced resonance conversions are analyzed. It is demonstrated that in the case of the super flares one may detect the depletion of the ν eL neutrinos caused by their resonance absorptions when they travel through the CS magnetic fields. Observations of this phenomena could be carried out at neutrino telescopes of the next generation whose work is based on the reaction of the coherent elastic neutrino-nucleus scattering.

Estimations of heavy neutrino masses and mixing in models with an extended Higgs sector

Within two-flavor approximation for the left right model, the equations connecting the parameters of the heavy neutrino sector and the charged Higgs sector (CHS) are found. For definition of the CHS parameters the impact of the Higgs bosons on lepton flavor violation decays, low-energy light neutrino scattering, and the muon anomalous magnetic moment are investigated. It is shown, that the heavy neutrino masses m N 1;2 can be expressed in terms of the triplet Yukawa coupling constants and the mass of the W 2 gauge boson only. Using the data of inverse muon decays, and also the constraints on the masses of the ÿ , ÿ 1;2 and W 2 bosons the limits on m N 1;2 are established in the cases both of the absence and the presence of the heavy neutrino masses (quasi)degeneration. The data on explanation of the g ÿ 2 anomaly is used for determination of the constraints on m N 1;2 in the case of the masses (quasi)degeneration only. The suggested scheme for estimations of the heavy neutrino masses and mixing, based on the Higgs sector investigation, can be used for any gauge electroweak theory with an extended Higgs sector and the ''see-saw'' mechanism.

In this paper, we investigate the evolution of the neutrino flux propagating through dense matter and an intensive magnetic field. As an example, the magnetic field of the coupled sunspots being the sources of solar flares is considered. We assume that neutrinos possess dipole magnetic and anapole moments while the magnetic field is twisting and nonpotential, and its strength may be ≥10 5 Gs. The problem is investigated within three neutrino generations. Possible resonance conversions inside the neutrino flux are studied.
