Neutrino Backgrounds to Dark Matter Searches and Directionality Citation
Neutrino-nucleus coherent scattering cross sections can be as large as 10−39 cm, while current dark matter experiments have sensitivities to WIMP coherent scattering cross sections several orders of magnitude smaller. With large target masses and few keV recoil energy detection thresholds, coherent scattering of solar neutrinos becomes an irreducible background. Directional dark matter detectio...
متن کاملNew DAMA dark-matter window and energetic-neutrino searches
Recently, the DAMA/LIBRA Collaboration has repeated and reinforced their claim to have detected an annual modulation in their signal rate, and have interpreted this observation as evidence for dark-matter particles at the 8:2 confidence level. Furthermore, it has also been noted that the effects of channeling may enable a weakly interacting massive particle (WIMP) that scatters elastically via ...
متن کاملDark Matter Searches
I'll start with a summary of the relevant evidence for cold dark matter from astrophysics and cosmology. The Standard Model of subnuclear physics does not have any dark matter particle, but its simplest extensions, the SUSY models, do have a very apt candidate, the neutralino. I will then briefly summarise the status and the expectations for the next years of indirect searches both with earth-b...
متن کاملDark Matter searches and Colliders
We study the potential of neutralino dark matter searches and SUSY particle production at colliders in the framework of the Minimal Supersymmetric Standard Model. We show the effects of a non universal gluino mass parameter. The future experiments will be a stringent probe of the low energy MSSM and neutralino dark matter scenario. The deeper informations on both supersymmetry and astrophysics ...
متن کاملCosmological gamma ray and neutrino backgrounds due to neutralino dark matter annihilation
We compute the cosmological background radiation of gamma rays and neutrinos due to neutralino annihilation in evolving dark matter halos, assuming the observed dark matter is comprised of thermally excited neutralinos in the MSSM. The spectrum of this gamma-ray background radiation does not show strong annihilation line features, but could amount to a significant fraction of the extragalactic ...
