Abstract: We investigate neutralino dark matter in the framework of NMSSM performing ascan over its parameter space and calculating neutralino capture andannihilation rates in the Sun. We discuss the prospects of searches forneutralino dark matter in neutrino experiments depending on neutralino contentand its main annihilation channel. We recalculate the upper limits onneutralino-proton elastic cross sections directly from neutrino telescopesupper bounds on annihilation rates in the Sun. This procedure has advantages ascompared with corresponding recalcalations from the limits on muon flux,namely, it is independent on details of the experiment and the recalculationcoefficients are universal for any kind of WIMP dark matter models. We derive90% c.l. upper limits on neutralino-proton cross sections from the results ofthe Baksan Underground Scintillator Telescope.
