Combination of D0 measurements of the top quark mass

Abstract

We present a combination of measurements of the top quark mass by the D0 experiment in the lepton þ jets and dilepton channels. We use all the data collected in Run I (1992–1996) at ffiffi s p ¼ 1.8 TeV and Run II (2001–2011) at ffiffi s p ¼ 1.96 TeV of the Tevatron pp¯ collider, corresponding to integrated luminosities of 0.1 fb−1 and 9.7 fb−1, respectively. The combined result is: mt ¼ 174.95 0.40ðstatÞ 0.64ðsystÞ GeV ¼ 174.95 0.75 GeV.
