A search for a heavy neutral boson

Search for a heavy Higgs boson decaying into a $Z$ boson and another heavy Higgs boson in the $\ell\ell bb$ and $\ell\ell WW$ final states in $pp$ collisions at $\sqrt{s}$ = 13 TeV with the ATLAS detector

A search for a heavy neutral neutral higgs boson, decaying into a boson and another heavy neutral neutral boson, is performed using a data sample correspondingto an integrated luminosity of 139 from proton-proton collisions at = 13 tev recorded by the atlas detector at the lhc.

The upper limits are in the range 0.0062-0.380 pb for the channel and in the range 0.023-8.9 pb for the channel.

An interpretation of the results in the context of two-higgs-doublet models is also given.
