Recent Sattelite experiments like WMAP & PLANCK precisely measured the dark matter components to be 26.8 % of the total energy budget of the universe.Infact it is supported by the indirect observations, such as galaxy collision in the bullet cluster,gravitational lensing and the rotational curve. However the existence of dark matter cannot be explained within the Standard Model of Prticle Physics.In this thesis we studied a viable solution of dark matter by extending the standard model with vector like Leptons.In particular we studied two scenarioes.
