【 摘 要 】

A detailed analysis of a minimal S3-invariant extension of the Standard Model including an extended S3-Higgs sector is performed. In this model, we study the trilinear Higgs couplings and its dependence on the details of the model, even when the lightest Higgs boson mass is taken to be a fixed parameter. We study quantitatively the trilinear Higgs couplings, and compare these couplings to the corresponding Standard Model trilinear Higgs coupling in some regions of the parameter space. A precise measurement of the trilinear Higgs self coupling will also make it possible to test this extended S(3)-Standard Model which has a different trilinear Higgs couplings as compared to the Standard Model. Finally, partial numerical results of the phenomenological Higgs effects are presented.
