Detection of the minimal supersymmetric model Higgs boson H0 in its h0h0 → 4b and A0A0 → 4b decay channels

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 (mA0, tan β) model parameter space. At low mA0 (≲ 60 GeV), both the H0 → A0A0 → 4b and H0 → h0h0 → 4b modes yield a viable signal for most tan β values; viability for the h0h0 channel extends up to mη0 ≈ mt when the model parameter tan β is not large. At the Tevatron, the h0h0 and A0A0 channels are both potentially viable at low mA0 for sufficiently good b-tagging efficiency and purity.
