Abstract

In this work was studied how dark matter can be captured by celestial bodies and how it can communicate with the Standard Model through its annihilation in quarks and leptons. The hadrons and leptons generated can decay in to neutrinos which can be detected by experiments in Earth. As three types of neutrino flavor eigenstates have been observed experimentally and many experimental data have shown the flavor neutrino oscillate, it is necessary use this phenomenology when studying neutrinos produced by Dark Matter. The formalism that allows considering neutrino oscillations and, at same time, elastic and inelastic matter collisions is the density matrix formalism. With this formalism we studied the muons flux produced by neutrinos coming from dark matter annihilation inside the sun and how to use these results to test particle models for dark matter. (AU)
