\Title{Search for Standard Model Production of Four Top Quarks}

\Author{Caleb Fangmeier}

\Institution{Department of Physics and Astronomy\\ University of Nebraska-Lincoln}

\Abstract{This talk describes efforts towards a first measurement of the standard model production of four top quarks with results based on up to the full Run 2 dataset. It includes implications of this measurement to constrain properties of the Higgs Boson and new physics scenarios including dark matter.}

\section{Introduction}

Four top quark production is a rare Standard Model process with a cross section of $\sigma\left(\mathrm{pp}\rightarrow t\bar{t}t\bar{t}\right)=12\mathrm{fb}$ calculated at next-to-leading order at 13TeV center of mass energy\cite{}. The dominant production mode of $t\bar{t}t\bar{t}$ at the LHC is through QCD diagrams such as those shown in Figure~\ref{fig:feyn_qcd}.
