Status of the MSW Solutions to the Solar Neutrino Problem

Abstract

In this talk we present the results of an updated global analysis of two-flavor MSW solutions to the solar neutrino problem in terms of conversions of ${\nu }_e$ into active or sterile neutrinos including the the full data set corresponding to the 825-day Super-Kamiokande data sample as well as to Chlorine, GALLEX and SAGE experiments.
