We computed the helicity amplitudes for Z0→Hgg. The decay rate Γ(Z0→Hgg) decreases relatively slowly as the Higgs mass mH increases. As a result, Z0→Hgg contributes significantly to Z0→H+jet+jet for mH≳50 GeV. With the kinematical cut φ{symbol}≥20° for the angle φ{symbol} between the two jets, we estimated the branching ratio B(Z0→H+jet+jet→τ+τ-+jet+jet) to be around 10-6 for mH≈40 GeV and to decrease to 10- for mH≈70 GeV.
