| Can be e.g. motivated by h -> Z a (with a -> DM DM, pseudo-scalar portal to DM), by h -> Z Z' (again, with a dark Z'), by h -> chi1 chi2 (with fermion/scalar chi1 invisible). Challenging since if the Higgs is not produced in association with another object, this is just Z + small E_T^miss (~ 20 GeV). SM Higgs decay h -> Z Z* -> Z vv constitutes possible sensitivity floor, corresponding to a BR(h->Z+E_T^miss) = 0.4 %. | Can be e.g. motivated by h -> Z a (with a -> DM DM, pseudo-scalar portal to DM), by h -> Z Z' (again, with a dark Z'), by h -> chi1 chi2 (with fermion/scalar chi1 invisible).

| - | Possible to probe the decay via p p -> Z h -> 4l + E_T^miss? | + | Possible to probe the decay via p p -> Z h -> 4l + E_T^miss? Quite small rate ~ 4 fb times BR(h->Z+E_T^miss). SM background ZZ -> 4l cross section is ~ 35 fb, so maybe possible. Alternative option to probe same physics in mono-Higgs: p p -> Z* -> h + E_T^miss. |
