We calculate the spinor helicity amplitudes of anomalous decay. After embedding these analytic formulas into the MCFM package, we study the interference effects between the anomalous process and the SM processes, which are indispensable in the Higgs off-shell region. Subsequently, the constraints on the anomalous couplings are estimated using LHC experimental data.
