# 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

### Description

We present a measurement of the t{bar t} production cross section in p{bar p} collisions at {radical}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 t{bar t} 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 fb{sup -1} of integrated luminosity. Based on 248 candidate events with three or more jets and an expected background of 79.5 {+-} 5.3 events, we measure a production cross section of 9.1 ... continued below
