Contribution
It provides the most recent combined measurement of the top quark mass from Tevatron data, including results from different decay channels and collaboration methods.
Findings
Top quark mass measured as 175.6 ± 6.8 GeV/c^2 (CDF)
Top quark mass measured as 172.1 ± 7.1 GeV/c^2 (D0)
Combined Tevatron measurement is 173.9 ± 5.2 GeV/c^2
Abstract
In this paper, we report on the most recent measurements of the top quark mass, performed by the CDF and D0 collaborations at the Fermilab Tevatron. The CDF collaboration has performed measurements of the top quark mass in three decay channels from which the top quark mass is measured to be 175.6 +- 6.8 GeV/c^2. The D0 collaboration combines measurements from two decay channels to obtain a top quark mass of 172.1 +- 7.1 GeV/c^2. Combining the measurements from the two experiments, assuming a 2 GeV/c^2 correlated systematic uncertainty, the measurement of the top quark mass at the Tevatron is 173.9 +- 5.2 GeV/c^2. This report presents the measurements of the top quark mass from each of the decay channels which contribute to this measurement.
