The angular power spectrum of the cosmic microwave background ~CMB! contains information on virtually all cosmological parameters of interest, including the geometry of the Universe ( V), the baryonâ€¦ (More)

We compare the rate for elastic scattering of neutralinos from various nuclei with the ux of upward muons induced by energetic neutrinos from neutralino annihilation in the Sun and Earth. We considerâ€¦ (More)

Variations in V, the total density of the Universe, leave an imprint on the power spectrum temperature fluctuations in the cosmic microwave background (CMB). We evaluate the precisio which V can beâ€¦ (More)

We present a complete calculation of the cross section for neutralino annihilation into the two-gluon final state. This channel can be quite important for the phenomenology of neutralino annihilationâ€¦ (More)

Weakly interacting massive particles (WIMPs) may be indirectly detected by observation of upward muons induced by energetic neutrinos from annihilation of WIMPs that have accumulated in the Sunâ€¦ (More)

Cosmological constraints on grand unified theories with spontaneous lepton number violation are analysed. We concentrate on SO(10), the simplest of the models possessing this property. It has beenâ€¦ (More)

We calculate the ux of cosmic gamma rays expected from the annihilation of neutralinos in the Galactic halo. Our calculation of the annihilation cross section to two photons improves the existingâ€¦ (More)
