Description

A search for a heavy resonance pseudo-scalar, A, decaying into a $Z$ boson and another heavy scalar boson, $H$, is carried out at the LHC using a data sample corresponding to an integrated luminosity of 139 fb$^{-1}$ from proton-proton collisions at $\sqrt{s}$ = 13 TeV. In these studies, the scalars $H$ will decay to two scalars $S$ or an $S$ and a Standard Model Higgs boson $H$ via an effective model. The $A \rightarrow Z(\rightarrow \ell\ell) $ and $ H (H\rightarrow SS $ or $Sh)$ production in at least four leptons final state will be examined in this search.
