The signature is a pair of $Z$ bosons, with contributions from both the production and subsequent decay of a virtual Higgs boson and the interference of that process with other processes. The two observable final states are $ZZ\\rightarrow 4\\ell$ and $ZZ\\rightarrow 2\\ell2\\nu$ with $\\ell = e$ or $\\mu$.
