Combination of CDF and D0 Results on the Top-Quark Mass

TL;DR

This paper combines top-quark mass measurements from CDF and D0 experiments at Fermilab, providing a precise world average with detailed uncertainty analysis based on Run I data.

Contribution

It presents a combined analysis of top-quark mass results, properly accounting for correlated uncertainties, to produce a refined world average value.

Findings

World average top-quark mass: 178.0 GeV/c^2

Total uncertainty: 4.3 GeV/c^2

Uncertainty breakdown: statistical 2.7, systematic 3.3

Abstract

The results on the measurements of the top-quark mass, based on the data collected by the Tevatron experiments CDF and DO at Fermilab during Run I from 1992 to 1996, are summarized. The combination of the published results, taking correlated uncertainties properly into account, is presented. The resulting world average for the mass of the top quark is: $M_t = 178.0 \pm 4.3 GeV/c^2$, where the total error of consists of a statistical part of $2.7 GeV/c^2$ and a systematic part of $3.3 GeV/c^2$.
