Measurement of the ttbar Production Cross Section in ppbar Collisions at sqrt(s)=1.96 TeV using Lepton + Jets Events with Lifetime b-tagging

D0 Collaboration, V. Abazov

We present a measurement of the top quark pair ($t\bar{t}$) production cross section (${\sigma }_{t\bar{t}}$) in $p\bar{p}$ collisions at $\sqrt{s}=1.96$ TeV using 230 pb${}^{-1}$ of data co…
