Title: Searching for additional Higgs bosons via Higgs cascades

Abstract

The discovery of a 125 GeV Higgs boson at the Large Hadron Collider strongly motivates direct searches for additional Higgs bosons. In a type I two Higgs doublet model there is a large region of parameter space at $$\mathrm{tan}{\beta}{\gtrsim}5$$ that is currently unconstrained experimentally. We show that the process $$gg{\rightarrow}H{\rightarrow}AZ{\rightarrow}ZZh$$ can probe this region, and can be the discovery mode for an extended Higgs sector at the LHC. We analyze 9 promising decay modes for the $ZZh$ state, and we find that the most sensitive final states are $${\ell}{\ell}{\ell}{\ell}bb$$, $${\ell}{\ell}jjbb$$, $${\ell}{\ell}{\nu}{\nu}{\gamma}{\gamma}$$ and $${\ell}{\ell}{\ell}{\ell}+$$ missing energy.
