THE FEYNMAN-LIKE PROCEDURE OF ORDERED EXPONENTIAL OPERATORS APPLIED TO SOLAR NEUTRINOS

An analytic resonant solution to the solar neutrino problem induced by small solar magnetic field phase velocity is derived using the Feynma n-like procedure of ordered exponential operators. We assume the stand ard solar model matter distribution inside the Sun and the model propo sed by Akhmedov and Bychuk for the solar magnetic field to conclude th at a neutrino magnetic moment of order (5-8) x 10(-13)mu(B) is suffici ent to explain the experimentally observed solar neutrino deficit, an improvement by a factor (2-4) relative to the conventional resonant sp in-precession solution induced by neutrino squared mass difference whe n the same solar characteristics are considered.
