Table 2.

Expected background yields and observed counts of data events after all selections for the ggF and VBF channels of the $H\to ZZ\to {\ell }^{+}{\ell }^{-}\mathit{\nu }\overline{\mathit{\nu }}$ search. The first and second uncertainties correspond to the statistical and systematic uncertainties, respectively
