The Solar Neutrino Problem in the Presence of Flavor Changing Neutrino Interactions

Abstract

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 $Delta{m}^2-si{n}^{2}2theta$ plane that are consistent with the four solar neutrino experiments are modified for different strengths of New Physics neutrino interactions.
