Measurement of the Top Quark Pair Production Cross Section in the Di-Electron+Jets Channel at D{\O}

ORAL

Abstract

Measurement of the top quark pair ($t\bar{t}$) production cross section at hadron colliders can be used to test perturbative QCD predictions. Within the Standard Model, the top quark almost always decays to a $W$ boson and a $b$ quark. We present a measurement of the $t\bar{t}$ production cross section at $\sqrt{s}=1.96$ TeV in $p\bar{p}$ collisions using about 370 pb$^{-1}$ of data collected by the D\O\ experiment during Run II of the Fermilab Tevatron collider. We consider the di-electron+jets final state and discuss the selection criteria, efficiencies and background contributions.
