Abstract

We present an analytical calculation of the next-to-next-to-leading order corrections to the partial decay width HggH\to gg for a Higgs boson in the intermediate mass range. We apply an asymptotic expansion for MH2MtM_H\ll 2M_t and compute three terms in the expansion. The leading term confirms the results present in the literature. It is argued that our result is equivalent to an exact calculation up to MHMtM_H\approx M_t. For a Higgs boson mass of 120 GeV the power-suppressed terms lead to corrections of about 9% in the next-to-next-to-leading order coefficient.
