Supersymmetric Heavy Higgses at e^+e^- Linear Collider and Dark-Matter Physics
arXiv:hep-ph/0509196 · doi:10.1103/PhysRevD.72.115012
Abstract
We consider the capability of the e^+e^- linear collider (which is recently called as the International Linear Collider, or ILC) for studying the properties of the heavy Higgs bosons in the supersymmetric standard model. We pay special attention to the large \tanβregion which is motivated, in particular, by explaining the dark-matter density of the universe (i.e., so-called ``rapid-annihilation funnels''). We perform a systematic analysis to estimate expected uncertainties in the masses and widths of the heavy Higgs bosons assuming an energy and integrated luminosity of \sqrt{s}=1 TeV and L=1 ab^{-1}. We also discuss its implication to the reconstruction of the dark-matter density of the universe.
