  "abstract": "We compute the order $\\alpha_s$ QCD corrections to the density matrix for the decay of a neutral Higgs boson $\\phi$ with (in)definite CP parity into a quark antiquark pair, respectively the QED corrections for the decay into a pair of charged leptons. We classify and calculate single spin asymmetries and spin-spin correlations which are generated by the scalar and pseudoscalar Yukawa couplings. These spin effects can be traced in $\\phi \\to \\tau^-\\tau^+$ and, for heavy Higgs bosons, in $\\phi \\to t\\bar{t}$. We also calculate resulting correlations among the final states and estimate, for the respective decay modes, the number of events needed to measure the Yukawa couplings with these correlations at the 3 sigma level.",
