Anomalous H ZZ 4 decay and its interference effects at the LHC
Abstract
We calculate the spinor helicity amplitudes of anomalous H ZZ 4 decay. After embedding these analytic formulas into the MCFM package, we study the interference effects between the anomalous gg H ZZ 4 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.
