Abstract: (APS)
For a conventional Higgs boson the decay correlation function for the azimuthal angle between the two W decay planes is F(φ)=1+αcosφ+βcos2φ, where α=(3π/8)2γ/(1+γ2/2), β=1/41/(1+γ2/2), with γ=(MH2-2mW2). While β is negligible, there will be a decay correlation fom α if MH is not too large (α≥1/4 if MH≤400 GeV). By α≠0, the standard g→v coupling is distinguished from the complete decoupling of a Higgs boson from transverse W bosons. For a technipion α=0, but uniquely β=-(1/4. For the Z pair decay mode, α contains an extra factor of 2r/(1+r2) from each Z→f¯f, where r is the ratio of the axial-vector- to the vector-coupling coefficients. This suppresses α since 2r/(1+r2)≃1/√2¯ for d¯d,≃-1/3 for u¯u, and ≃1/4 for μ+μ−.- HIGGS PARTICLE: DECAY
