DARK MATTER AND IT'S DETECTION AT TERRESTRIAL LABORATORIES.
Masters thesis, Indian institute of technology Hyderabad.
Abstract
The work for this dissertation is two-fold, rst to understand the Standard Model(SM) and then looking for physics of Dark matter (DM) which is beyond the Standard model. We discuss Standard Model as a gauge theory where abelian and non-abelian gauge theory are thoroughly discussed. Then we move to electroweak sector where we discuss the interaction of intermediate vector bososns and fermions. Also we show how using Electroweak symmetry breaking and Higgs mechanism, we can give mass to SM particles. After this rst part we move to our second part which is DM physics. We derive the DM relic density in the expanding universe using Boltzmann equation. Then we concentrate our work on the direct detection of DM where we calculate the DM-nucleus scattering cross section, which is used in the terrestrial laboratories for the detection of DM.
