The solar neutrino problem and Non Standard Interactions

摘要

We analize the solar neutrino data to obtain constraints on physics beyond the Standard Model. We use the framework of non standard interactions in the neutrino sector. This formalism is an useful tool to study physics beyond the Standard Model. In particular we concentrate on the diagonal neutrino couplings to electrons. We perform a phenomenological analysis by considering data from Super-Kamiokande, SNO and radiochemical solar experiments and combine them with the KamLAND results. We conclude that this analysis can improve current constraints on non standard interactions parameters.
