\begin{document}$H\to ZZ \to 4\ell$\end{document} decay. After embedding these analytic formulas into the MCFM package, we study the interference effects between the anomalous \begin{document}$gg\to H\to ZZ \to 4\ell$\end{document} 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."> Anomalous <inline-formula><tex-math id="M1">\begin{document}${{H\to ZZ \to 4\ell}}$\end{document}</tex-math><alternatives><graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/hepnp/article/app/id/ef091609-a3d8-428a-8a22-3223d29404de/CPC-2020-0027_M1.jpg"/><graphic xmlns:xlink="http://www.w3.org/1999/xlink" xlink:href="//www.macurncorp.com/hepnp/article/app/id/ef091609-a3d8-428a-8a22-3223d29404de/CPC-2020-0027_M1.png"/></alternatives></inline-formula> decay and its interference effects on gluon–gluon contribution at the LHC -
