Search for heavy neutral Higgs bosons A and H in the $\mathrm{t}\bar{\mathrm{t}}$Z channel in proton-proton collisions at 13 TeV

CMS Collaboration

A direct search for new heavy neutral Higgs bosons A and H in the $\mathrm{t}\bar{\mathrm{t}}$Z channel is presented, targeting the process pp $\to$ A $\to$ ZH with H $\to$ $\mathrm{t\bar{t…
