Measurements of the top quark mass with the D0 detector

The mass of the top quark is a fundamental parameter of the standard model (SM) and has to be determined experimentally. In this talk, I present the most recent measurements of the top quark mass in p p collisions at √ s=1.96 TeV recorded by the D0 experiment at the Fermilab Tevatron Collider. The measurements are performed in final states containing two leptons, using 5.4 of integrated luminosity, and one lepton, using 9.7 of integrated luminosity. The latter constitutes the most precise single measurement of the mass of the top quark, corresponding to a relative precision of 0.43%. I conclude with a combination of our results with the results by the CDF collaboration, attaining a relative precision of 0.37%
