# Combination of D0 measurements of the top quark mass

## TL;DR

This paper combines multiple measurements from the D0 experiment to provide a precise estimate of the top quark mass, utilizing data from two different run periods at the Tevatron collider.

## Contribution

It presents the first combined top quark mass measurement from D0 using all available Run I and Run II data, improving precision over individual measurements.

## Key findings

- Top quark mass measured as 174.95 GeV
- Total uncertainty of 0.75 GeV
- Results are consistent with previous measurements

## Abstract

We present a combination of measurements of the top quark mass by the D0 experiment in the lepton+jets and dilepton channels. We use all the data collected in Run I (1992--1996) at $\sqrt s=1.8$ TeV and Run II (2001--2011) at $\sqrt s=1.96$ TeV of the Tevatron $p \bar{p}$ collider, corresponding to integrated luminosities of 0.1 fb$^{-1}$ and 9.7 fb$^{-1}$, respectively. The combined result is: $m_t = 174.95 \pm0.40\,{\rm(stat)} \pm 0.64\,{\rm(syst)}\,{\rm{GeV}}=174.95 \pm 0.75 \, {\rm{GeV}}$.
