A search is presented for new particles in an extension to the Standard Model that includes a heavy Higgs boson (${H}^{0}$), an intermediate charged Higgs-boson pair (${H}^{\ifmmode\pm\else\textpm\fi{}}$), and a light Higgs boson (${h}^{0}$). The analysis searches for events involving the production of …
