Neutrino constraints on inelastic dark matter after CDMS II results

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) < 100 GeV) and have a large DM-nucleon cross section (sigma(n) similar to 10(-4) pb in the spin-independent (SI) scattering and sigma(n) similar to 10 pb in the spin-dependent (SD) scattering). The dominant contribution to the iDM capture in the Sun is from scattering off Fe/Al in the SI/SD case. Current bounds from Super-Kamiokande exclude the hard DM annihilation channels, such as W+W-, ZZ, t<(t)over bar>, 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.
