Implications of a possible 115 GeV supersymmetric Higgs boson on detection and cosmological abundance of relic neutralinos
A. Bottino, N. Fornengo, S. Scopel
We show that a supersymmetric neutral Higgs boson with a mass of about 115 GeV and with the other prerequisites required by the LEP Higgs events would be compatible with the detect…
Neutrino Oscillation Effects in Indirect Detection of Dark Matter
Nicolao Fornengo
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 signa…
Probing the supersymmetric parameter space by WIMP direct detection
A. Bottino, F. Donato, N. Fornengo +1
We discuss to which extent the present experiments of direct search for WIMPs, when interpreted in terms of relic neutralinos, probe interesting regions of the supersymmetric param…
Updated Global Analysis of the Atmospheric Neutrino Data in terms of neutrino oscillations
N. Fornengo, M. C. Gonzalez-Garcia, J. W. F. Valle
A global analysis of all the available atmospheric neutrino data is presented in terms of neutrino oscillations in the nu_mu -> nu_tau and nu_mu -> nu_s channels, where nu_s denote…
Further investigation of a relic neutralino as a possible origin of an annual-modulation effect in WIMP direct search
A. Bottino, F. Donato, N. Fornengo +1
We analyze the annual-modulation effect, measured by the DAMA Collaboration with the new implementation of a further two-years running, in the context of a possible interpretation…
Relic neutralinos: update on neutralino-nucleon scalar cross-section
Nicolao Fornengo
We discuss the effect induced on the neutralino-nucleon scalar cross-section by the present uncertainties in the values of the quark masses and of the quark scalar densities in the…
Standard and exotic interpretations of the atmospheric neutrino data
Nicolao Fornengo
The present status of some theoretical interpretations of the atmospheric neutrino deficit is briefly discussed. Specifically, we show the results for the FC mechanism and for the…
