1 Introduction to thesis
Several observations ranging from star clusters to the cosmological scale are in favour of the existence of an unknown non-luminous matter, or dark matter (DM) [3,31–38]. Data from WMAP [37], PLANCK [39], which probe anisotropies in cosmic microwave background radiation (CMBR), emphasize that the total mass-energy of the universe contains 4.9% ordinary matter (Baryonic matter), 26.8% dark matter, and 68.3% of an unknown form of energy called dark energy. However, only gravitational effects of DM have been observed to date; hence, the particle nature of DM is largely unknown.
\ This thesis focuses on the various WIMP models of DM. In the first chapter, we discuss the basics of DM. The chapter is organized as follows: In section 1.1, we discuss the strong evidence that historically supports this unknown matter. Section 1.2, we collect some of the known facts and features about DM. Section 1.3 briefly discusses several popular dark matter candidates. In the last section 1.4, we discuss three main detection techniques for DM.
