Measurement of the $\ttbar$ Production Cross Section in 2 fb${}^{-1}$ of $\ppbar$ Collisions at $\sqrt{s}=1.96$ TeV Using Lepton Plus Jets Events with Soft Muon b-Tagging

Abstract

We present a measurement of the $\ttbar$ production cross section in $\ppbar$ collisions at $\sqrt{s}=1.96$ TeV using events containing a high transverse momentum electron or muon, three or more jets, and missing transverse energy. Events consistent with $\ttbar$ decay are found by identifying jets containing candidate heavy-flavor semileptonic decays to muons. The measurement uses a CDF Run II data sample corresponding to $2\mathrm{f}{\mathrm{b}}^{-1}$ of integrated luminosity. Based on 248 candidate events with three or more jets and an expected background of $79.5\pm 5.3$ events, we measure a production cross section of $9.1\pm 1.6\mathrm{pb}$.
