On Solar Neutrino Problem

چکیده
The current neutrino oscillation theory asserts that neutrinos are massive subatomic particles, and can undergo their flavor oscillation. First in this article, we examine carefully the current oscillation theory, and argue that a massless neutrino oscillation mechanism based on the Weyl equations for neutrinos is also a feasible theory. This massless neutrino oscillation mechanism resolves both the parity problem and the handedness and speed of neutrino problem, which the current massive neutrino oscillation mechanism faces. Second, we propose a neutrino non-oscillation mechanism based on the weakton model of subatomic particles, providing an alternative resolution to the solar neutrino loss problem.

Is bi-maximal mixing compatible with the large angle MSW solution of the solar neutrino problem?
It is shown that the large angle MSW solution of the solar neutrino problem with a bi-maximal neutrino mixing matrix implies an energy-independent suppression of the solar νe flux. The present solar neutrino data exclude this solution of the solar neutrino problem at 99.6% CL.
متن کاملAstroparticle physics with solar neutrinos
Solar neutrino experiments observed fluxes smaller than the expectations from the standard solar model. This discrepancy is known as the "solar neutrino problem". Flux measurements by Super-Kamiokande and SNO have demonstrated that the solar neutrino problem is due to neutrino oscillations. Combining the results of all solar neutrino experiments, parameters for solar neutrino oscillations are o...
متن کاملStatus and prospects of MSW and vacuum oscillation solutions of the solar neutrino problem
The current interpretation of the solar neutrino problem in terms of MSW or vacuum oscillations depends signiicantly on the absolute neutrino uxes, i.e., on solar model calculations. However, second-generation experiments such as SuperKamiokande, SNO, and Borexino, will be able to test these neutrino oscillation solutions independently of solar models. We discuss the theoretical estimates and t...
متن کاملNew constraints on neutrino oscillations in vacuum as a possible solution of the solar neutrino problem.
Two-neutrino oscillations in vacuum are studied as a possible solution of the solar neutrino problem. New constraints on the parameter sin 2θ, characterizing the mixing of the electron neutrino with another active or sterile neutrino, as well as on the mass–squared difference, ∆m2, of their massive neutrino components, are derived using the latest results from the four solar neutrino experiment...
متن کاملThe Charged Neutrino: a New Approach to the Solar Neutrino Problem
We have considered the effect of the reduction of the solar neutrino flux on earth due to the deflection of the charged neutrino by the magnetic field of the solar convective zone. The antisymmetry of this magnetic field about the plane of the solar equator induces the anisotropy of the solar neutrino flux thus creating the deficit of the neutrino flux on the earth. The deficit has been estimat...
متن کاملThe Solar Neutrino Problem in the Presence of Flavor Changing Neutrino Interactions
We study the effects of flavor changing neutrino interactions on the resonant conversion of solar neutrinos. In particular, we describe how the regions in the ∆m − sin 2θ plane that are consistent with the four solar neutrino experiments are modified for different strengths of New Physics neutrino interactions.
