Measurement of the $t\bar{t}$ production cross section at D0 using $\tau$+jets events

We report on the measurement of the $t\bar{t}$ production cross section with candidate events in which the W boson from one of the top quarks decays into a $\tau$ lepton and the associated neutrino while the other $W$ boson decays to a quark-antiquark pair. We select events in which the $\tau$ lepton subsequently decays to one or three charged hadrons plus neutral hadrons and a neutrino.
