Neutrino oscillation effect on the indirect signal of neutralino dark matter from the Earth core
نویسنده
چکیده
We investigate the effect induced by neutrino oscillation on the dark matter indirect detection signal which consists in a muon neutrino flux produced by neutralino annihilation in the Earth core. We consider the neutrino oscillation parameters relevant to the atmosferic neutrino deficit, both in the νμ → ντ and νμ → νs cases.

متن کاملNeutrino Oscillation Effects in Indirect Detection of Dark Matter
If neutrino oscillation plays a role in explaining the atmospheric neutrino deficit, then the same phenomenon would necessarily affect also the dark matter indirect-detection signal which consists in a muon-neutrino flux produced by neutralino annihilation in the Earth core. In this paper we investigate to which extent the upgoingmuon signal originated by neutralinos captured inside the Earth w...
متن کاملAspects of Neutrino Detection of Neutralino Dark Matter
Neutralino dark matter, and in particular different aspects of its detection at neutrino telescopes, has been studied within the Minimal Supersymmetric extension of the Standard Model, the MSSM. The relic density of neutralinos has been calculated using sophisticated routines for integrating the annihilation cross section and the Boltzmann equation. As a new element, so called coannihilation pr...
متن کاملAtmospheric and Astrophysics Neutrinos with MACRO
MACRO can detect three topologies of neutrino induced events, corresponding to different parent neutrino energies. The most numerous sample is made of upward throughgoing muons induced by atmospheric neutrinos of average energy 100 GeV. The ratio of the observed over the expected events is 0.74 ± 0.036stat ± 0.046sys ± 0.13theor. The observed zenith distribution does not fit the expected one in...
