Indirect detection of Dark Matter through Neutrino signals coming from the Sun
Summary:
In this Master thesis Supersymmetry as a solution to the Dark Matter problem is presented and afterwards the way in which it can be detected is given. After a short mention of the Elementary Particles’ Standard Model, we begin building the Supersymmetric theory. At first, we define coherent conventions, which are conserved throughout the project, and after the needed analysis we result in the complete supersymmetric Lagrangian. The results are also reached with the help of the Superfield formalism. The discussion continues specializing for the Minimal Supersymmetric Standard Model (MSSM) and concepts such as the soft Supersymmetry breaking and the conservation of R-Parity are studied. At this point the mass matrices for all the MSSM's fresh particles are given in full form. Especial importance is given to the lightest Neutralino, which is assumed to be the Lightest Supersymmetric Particle (LSP). The Neutralino LSP is considered to be Dark Matter's main ingredient. LSP's interaction graphs lead onto calculations for its direct detection cross section. In this thesis we study the indirect detection of LSPs via neutrinos produced by their annihilations. We discuss a model in which those neutrinos are traced to come from the Sun, for there LSPs had been captured beforehand, while normally they were living in a Dark Matter galactic halo.
