متن کاملA closer look at CMB constraints on WIMP dark matter
We use Cosmic Microwave Background data from the WMAP, SPT, BICEP, and QUaD experiments to obtain constraints on the dark matter particle mass mχ, and show that the combined data requires mχ > 7.6 GeV at the 95% confidence level for the χχ→ bb̄ channel assuming s−wave annihilation and a thermal cross section 〈σav〉 = 3× 10−26 cm3/s. We examine whether the bound on mχ is sensitive to σ8 measuremen...
متن کاملCmb Constraints on a Baryonic Dark Matter-dominated Universe
In recent years, upper limits on the cosmic microwave background (CMB) anisotropies combined with predictions made by theories of galaxy formation, have been extremely powerful in ruling out purely baryonic dark matter (BDM) universes. However, it has recently been argued that the absence of a prominent second peak in the anisotropy spectrum measured by the BOOMERanG-98 and MAXIMA-1 experiments...
متن کاملUpper bound on the dark matter total annihilation cross section.
We consider dark matter annihilation into standard model particles and show that the least detectable final states, namely, neutrinos, define an upper bound on the total cross section. Calculating the cosmic diffuse neutrino signal, and comparing it to the measured terrestrial atmospheric neutrino background, we derive a strong and general bound. This can be evaded if the annihilation products ...
