-This note presents a new measurement of $p\bar p \to t \bar tX$ production 
+We present a new measurement of $p\bar p \to t \bar tX$ production 
 at $\sqrt{s}=1.96$ TeV using 4951.86 pb$^{-1}$ of data collected with the
-D\O\ detector between 2002 and 2010. We focus on the final state
+D0 detector between 2002 and 2010. We focus on the final state
 where the $W$ boson from one of the top quarks decays into a 
-$\tau$ lepton and its associated neutrino, while the other W boson decays into 
+$\tau$ lepton and its associated neutrino, while the other $W$ boson decays into 
 a quark-antiquark pair. We aim to select those events in which the
-$\tau$ lepton subsequently decays hadronically, meaning to one or three charged hadrons, zero
-or more neutral hadrons and a tau neutrino. We use a neural network b-tagging algorithm
-as well as a topological neural network to enhance signal over the background. For a top quark
-mass of 172.5 GeV the preliminary result for the measured cross section is:
