Supersymmetry and the Higgs sector of the Next-to Minimal SuperSymmetric Model

Abstract: The problems of the standard model are reviewed and the motivations for introducing supersymmetry are discussed. The basic theory behind supersymmetry is described briefly, followed by an introduction of two realistic supersymmetric models; the Minimal SuperSymmetric Model (MSSM) and its proposed extension, the NMSSM. Some details of the NMSSM are stated and some constraints on parameters are described. I then explore the Higgs boson masses and couplings for some interesting scenarios, including a few different ways of taking the limit where NMSSM reduces to MSSM.
