Abstract
SNO measurements strongly constrain the central temperature of the Sun, to within a precision of much less than . This result can be used to probe the parameter space of supersymmetric dark matter. In this first analysis we find a lower limit for the weakly interacting massive particle (WIMP) mass of 60 GeV. Furthermore, in the event that WIMPs create a quasi-isothermal core, they will produce a peculiar distribution of the solar neutrino fluxes measured on Earth. Typically, a WIMP with a mass of 100 GeV and annihilation cross section of will decrease the neutrino predictions, by up to for the Cl, by for the heavy water, and by for the Ga detectors.
