\bottomheading{$WW$+$ZZ$ interfering, process 8211} This process calculable at leading LO and next-to-leading order NLO. This process describes a specific final state which is accesible both from the decay to two $W$'s and two $Z$'s. The two processes can thus interfere. This process has been treated in several papers, \cite{Campbell:1999ah,Campbell:2011bn,Boughezal:2016wmq,Campbell:2022gdq}.
