Title: Precision measurement of the top-quark mass in lepton+jets final states

We measure the mass of the top quark in lepton$+$jets final states using the full sample of $$p\bar{p}$$ collision data collected by the D0 experiment in Run II of the Fermilab Tevatron Collider at $$\sqrt s=1.96 $$TeV, corresponding to $$9.7 {\rm fb}^{-1}$$ of integrated luminosity. We use a matrix element technique that calculates the probabilities for each event to result from $$t\bar t$$ production or background. The overall jet energy scale is constrained in situ by the mass of the $W$ boson. We measure $$m_t=174.98\pm0.76$$ GeV. In conclusion, this constitutes the most precise single measurement of the top-quark mass.
