Solar neutrino problem within the left-right model

Limiting ourselves to the two flavor approximation within the SU(2)LxSU(2)RxU(1)B-L gauge model the motion of the neutrino flux in solar matter is considered. For the neutrino system described by the eight-component wave function ΨT=(νeL,νXL,NeR,NXR ,bar νeR,bar νXL,bar NeR,bar NXR), where X=μ,τ, an evolution equation in a Schroedinger-like form is found. It is shown that the number of possible resonance transitions for the flux of solar νeL is defined both by the mass hierarchy within the system νeL,νXL,NeR,NXL, and by the choice of mixing scheme. Factors influencing the neutrino flux crossing a region of solar flares are defined. copyright 1996 The American Physical Society
