We study properties of the lightest neutralino (\chi) and calculate its cosmological relic density in a supersymmetric U(1)' model with a secluded U(1)' breaking sector (the S-model). The lightest neutralino mass is smaller than in the…
We compute the number of trilepton events to be expected at Fermilab as a result of the reaction $p\bar p\to\chi^\pm_1\chi^0_2X$, where $\chi^\pm_1$ is the lightest chargino and $\chi^0_2$ is the next-to-lightest neutralino. This signal is…

Weakly-interacting massive particles (WIMPs) annihilating in the center of the Sun or the Earth may give rise to energetic neutrinos which might be discovered by astronomical neutrino detectors. The angular distribution of the…
A procedure for studying low energy neutrinos processes using hadronic physics ideas is proposed. We describe how the neutrino-neutrino interactions can be modelled using massive gauge theories. The mass of the gauge bosons is created by…
GUT monopoles captured by the Sun's gravitation are expected to catalyze proton decays via the Callan-Rubakov process. In this scenario, protons, which initially decay into pions, will ultimately produce \nu_{e}, \nu_{\mu} and…

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 Sun and/or Earth. Energetic muon neutrinos come…

We show that LEPII will either discover charginos and neutralinos, or enable a very stringent upper limit to be placed on $\tan \beta$ as a function of the gluino mass. The only assumption we make is the existence of some unified model…
With no concrete evidence for non-gravitational interactions of dark matter to date, it is natural to wonder whether dark matter couples predominantly to the Standard Model (SM)'s neutrinos. Neutrino interactions (and the possible existence…
It is shown that from the data of future solar neutrino experiments (SNO and Super-Kamiokande), in which high-energy $^8\mathrm{B}$ neutrinos will be detected, it will be possible in a model independent way: 1) To reveal the presence of…
Neutrino telescopes are opening new opportunities in observational high energy astrophysics. In these detectors, atmospheric muons from primary cosmic ray interactions in the atmosphere play an important role. They provide the most abundant…
Cosmic voids, the underdense regions in the universe, are particularly sensitive to diffuse density components such as cosmic neutrinos. This sensitivity is enhanced by the match between void sizes and the free-streaming scale of massive…

Supersymmetric neutralinos are one of the most promising candidates for the dark matter in the Universe. If they exist, they should make up some fraction of the Milky Way halo. We investigate the fluxes of positrons expected at the Earth…

Indirect searches for signatures of corpuscular dark matter have been performed using all cosmic messengers: gamma rays, cosmic rays, and neutrinos. The search for dark matter from neutrinos is of particular importance since they are the…
We examine the cross sections for the elastic scattering of neutralinos $\chi$ on nucleons $p,n$, as functions of $m_\chi$ in the constrained minimal supersymmetric standard model. We find narrow bands of possible values of the cross…
