Using a sample of dilepton top-quark pair ($t\overline{t}$) candidate events, a study is performed of the production of top-quark pairs together with heavy-flavor (HF) quarks, the sum of $t\overline{t}+b+X$ and $t\overline{t}+c+X$, collectively referred to as $t\overline{t}\text{ }+\text{ }\mathrm{HF}$. The data set used …

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 …
