The higgs sector of the MSSM with general soft breaking terms

Abstract

This thesis is basically established upon an analysis of determining the effects of the non-holomorphic soft supersymmetry breaking terms on the mass spectrum of the minimal supersymmetric Standard Model (MSSM). We give an overview concerning the fundamental concepts of supersymmetry (SUSY) after providing a brief discussion about the problems of Standard Model (SM) of particle physics. Then we discuss in detail that SUSY is not the exact symmetry of nature and it must be broken. In general, the breakdown of the global supersymmetry is parameterized by a set of operators. These operators could be both holomorphic or non-holomorphic in structure. Hence, in theories like the (MSSM) that do not contain any gauge singlets, these non-holomorphic supersymmetry breaking terms are soft and do not pose any problem for gauge hierarchy.In this thesis, in particular we study the impacts of the non-holomorphic softbreaking with the chargino sector so as to single out the effects of non-holomorphic trilinear couplings from the . parameters. Since the aforementioned sectors are two of the prime concerns of experiments at the LHC, we expect that our results will be testable in near future.
