New (and Old) Perspectives on Higgs Physics

Abstract

Old and new ideas regarding Higgs physics are reviewed. We first summarize the quadratic divergence / hierarchy problem which strongly suggests that the SM Higgs sector will be supplemented by new physics at high scales. We next consider means for delaying the hierarchy problem of the SM Higgs sector to unexpectedly high scales. We then outline the properties of the most ideal Higgs boson. The main advantages of a supersymmetric solution to the high scale problems are summarized and the reasons for preferring the next-to-minimal supersymmetric model over the minimal supersymmetric model in order to achieve an ideal Higgs are emphasized. This leads us to the strongly motivated scenario in which there is a Higgs hh with SM-like WW,ZZWW,ZZ couplings and \mh100\gev\mh\sim 100\gev that decays via haah\to aa with ma<2mbm_a<2m_b, where ma>2mτm_a>2m_\tau is preferred, implying aτ+τa\to \tau^+ \tau^-. The means for detecting an haa4τh\to aa\to 4\tau signal are then discussed. Some final cautionary and concluding remarks are given.
