Abstract

We computed the helicity amplitudes for Z⁰→Hgg. The decay rate Γ(Z⁰→Hgg) decreases relatively slowly as the Higgs mass m_H increases. As a result, Z⁰→Hgg contributes significantly to Z⁰→H+jet+jet for m_H≳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 m_H≈40 GeV and to decrease to 10^- for m_H≈70 GeV.
