摘要: We discuss the neutrino constraints from solar and terrestrial dark matter (DM) annihilations in the inelastic dark matter (iDM) scenario after the recent CDMS II results. To reconcile the DAMA/LIBRA data with constraints from all other direct experiments, the iDM needs to be light (m(chi) , and tau(+)tau(-). For soft channels such as b (b) over bar and c (c) over bar, the limits are loose, but could be tested or further constrained by future IceCube plus DeepCore. For neutrino constraints from the DM annihilation in the Earth, due to the weaker gravitational effect of the Earth and inelastic capture condition, the constraint exists only for small mass splitting delta < 40 keV and m(chi) similar to (10, 50) GeV even in the tau(+)tau(-) channel.
