DENSITY PERTURBATIONS AND RESONANT CONVERSION OF NEUTRINOS

Abstract
The influence of local density perturbations on the resonant neutrino conversion is studied. General relations are established between the features of the perturbations and the changes in the conversion probabilities. In the extreme case of very fast changes of density in a thin layer, the problem is solved analytically. We consider the possibility of appearance or shift of local ρ-perturbations in the sun to induce appreciable variations of the solar neutrino signals, in particular in the Cl-Ar experiment.
