   <hidden TTP06-14  Top Quark Mediated Higgs Decay into Hadrons to Order $\alpha_s^5$ > We present in analytic form the O(alpha_s^5) correction to the H->gg
 partial width of the standard-model Higgs boson with intermediate mass
 M_H<2M_t. Its knowledge is useful because the O(alpha_s^4) correction
 is sizeable (around 20%). For M_H=120 GeV, the resulting QCD
 correction factor reads
 1 + (215/12) alpha_s^(5)(M_H)/pi
 + 152.5 (alpha_s^(5)(M_H)/pi)^2
 + 381.5 (alpha_s^(5)(M_H)/pi)^3
 \approx 1+0.65+0.20+0.02.
 The new four-loop correction increases the total Higgs-boson hadronic
 width by a small amount of order 1 promille and stabilizes
 significantly the residual scale dependence.
