Direct and Indirect Search for Dark Matter
Direct and indirect searches for dark matter (DM) particles are discussed. The search for a diffuse signal from DM annihilation in the Milky Way is presented using the atmospheric neutrino data from Super-Kamiokande-I, -II, -III. The analysis focuses on the model independent scenario with DM particles annihilating directly into pairs of neutrinos and antineutrinos. No signal contribution is all...
متن کاملSearch for Neutrino Mass and Dark Matter in Underground Experiments
In this lecture we shall discuss two central problems of particle physics and cosmology. The neutrino mass is one of the key quantities in grand unified theories, and at the same time candidate for hot dark matter in the Universe. Supersymmetry is regarded as the most natural extension of present particle physics theories. The lighest SUSY particle, usually assumed to be the neutralino, is the ...
متن کاملQuirky Composite Dark Matter
We propose a new dark matter candidate, “quirky dark matter,” that is a scalar baryonic bound state of a new non-Abelian force that becomes strong below the electroweak scale. The bound state is made of chiral quirks: new fermions that transform under both the new strong force as well as in a chiral representation of the electroweak group, acquiring mass from the Higgs mechanism. Electric charg...
متن کاملLittle composite dark matter
We examine the dark matter phenomenology of a composite electroweak singlet state. This singlet belongs to the Goldstone sector of a well-motivated extension of the Littlest Higgs with T-parity. A viable parameter space, consistent with the observed dark matter relic abundance as well as with the various collider, electroweak precision and dark matter direct detection experimental constraints i...
متن کاملA comparison between direct and indirect dark matter search
We carry out a comparison between different kinds of experiments for the detection of neutralino dark matter. In particular, we compare the theoretical predictions for the direct detection of these particles, through their elastic scattering on target nuclei through nuclear recoils, with those for their indirect detection through the gamma rays produced by their annihilation in the galactic cen...
