Some remarks on the Wolfenstein equation of neutrino oscillations in matter. Elastic interactions of neutrinos in matter and polarization of matter by neutrinos

The physics laying on the basis of the Wolfenstein equation, is analysed. For this purpose a photon, a massive charged particle and a massive neutrino passing through matter are studied. It is also shown that since the standard weak interaction cannot generate masses, it cannot generate permanent polarization of matter either, due to this reason the energy (W) of neutrino elastic interaction in matter in the Wolfenstein equation is zero. It leads to the conclusion: resonance enhancement of neutrino oscillations in matter does not exist. It is shown that in the standard weak interaction the Cherenkov radiation cannot exist. The hypothetical left-right symmetrical weak interaction, which is used in the Wolfenstein equation, can generate the resonance enhancement of neutrino oscillation in matter, but for stars the condition for realization of the resonance is not fulfilled. Moreover, it is shown that the neutrino resonance enhancement in matter must disappear without leaving a trace when neutrinos go out into vacuum from matter (the Sun)
