• Abstract:

  There are several good motivations to extend the scalar sector of the Standard Model (SM). Models with an extended scalar sector usually have new sources of CP violation. It is already established that the SM cannot account for the observed baryon asymmetry of the Universe requiring new sources of CP violation. Furthermore some of these extensions may also provide good dark matter candidates. In addition, the existence of a richer scalar sector has important implications for flavour physics. The directions of research pursued in this thesis work will depend on specific interests of the student and recent experimental and theoretical developments in this field.
