However, in \norder to give masses to these particles, the electroweak gauge symmetry must be broken. In the SM, this is achieved \nthrough the Higgs mechanism where a scalar Higgs field acquires a vacuum expectation value. It is well known that the \npresence of a scalar field in the SM leads to a hierarchy problem, and therefore the SM by itself can not be the \nfundamental theory of nature. A well-motivated extension of the SM which addresses this problem is the Minimal \nSupersymmetric Standard Model (MSSM).  The Higgs sector in the MSSM has a rich phenomenology and its predictions can \nbe tested at colliders. In this thesis, I will describe three examples in supersymmetric models where the Higgs \nphenomenology is significantly different from that in SM. The first example is the MSSM with large tan \u0392 where \nthe Higgs coupling to the bottom quarks receives large radiative supersymmetric QCD corrections. As a consequence, \nHiggs production in association with bottom quark can be a dominant Higgs production mode in certain parameter spaces \nof the MSSM. A second example is an extension of the MSSM wherein a fourth generation of chiral fermions and their \nsuper-partners are added. I will show that the Higgs boson in such models can be as heavy as ~ 500 GeV. Finally, as a \nthird example, the MSSM with one of the stops lighter than the top quark is considered. Such a scenario is required \nto generate sufficient baryon asymmetry in the universe through the process of electroweak baryogenesis. By using the \ncorrelations between the Higgs production and decay rates, it will be shown that the electroweak baryogenesis in the \nMSSM is highly constrained."},{"label":"dcterms.available","value":"2013-05-22T17:34:49Z"},{"label":"dcterms.contributor","value":"Dawson, Sally"},{"label":"dcterms.creator","value":"Jaiswal, \nPrerit"},{"label":"dcterms.dateAccepted","value":"2013-05-22T17:34:49Z"},{"label":"dcterms.dateSubmitted","value":"2015-04-24T14:46:47Z"},{"label":"dcterms.description","value":"Department of Physics"},{"label":"dcterms.extent","value":"147 \npg."},{"label":"dcterms.format","value":"Application/PDF"},{"label":"dcterms.identifier","value":"http://hdl.handle.net/1951/59702"},{"label":"dcterms.issued","value":"2012-08-01"},{"label":"dcterms.language","value":"en_US"},{"label":"dcterms.provenance","value":"Made available in DSpace on 2013-05-22T17:34:49Z (GMT).
