摘      要：We calculate the spinor helicity amplitudes of anomalous H→ZZ→4ℓ*** embedding these analytic formulas into the MCFM package,we study the interference effects between the anomalous gg→H→ZZ→4ℓprocess and the SM processes,which are indispensable in the Higgs off-shell ***,the constraints on the anomalous couplings are estimated using LHC experimental data.
