Abstract

We demonstrate that detection of the heavier minimal supersymmetric model CP-even Higgs boson H⁰ will be possible at the LHC via its H⁰→ h⁰h⁰→ 4b and/or H⁰→ A⁰A⁰→ 4b decay channels for significant portions of the ( m_A⁰,tanβ) model parameter space. At low m_A⁰ (\lsim 60\gev), \it both the H⁰→ A⁰A⁰→ 4b and H⁰→ h⁰h⁰→ 4b modes yield a viable signal for most tanβ values; viability for the h⁰h⁰ channel extends up to \mhh∼ 2\mt when the model parameter tanβ is not large. At the Tevatron, the h⁰h⁰ and A⁰A⁰ channels are both potentially viable at low m_A⁰ for sufficiently good b-tagging efficiency and purity.
