Top Quark Mass from CDF
P. Mehtala (The CDF Collaboration)
TL;DR
This paper reports a highly precise measurement of the top quark mass from CDF data, combining results from multiple runs and experiments, and discusses its implications for the Standard Model and Higgs boson predictions.
Contribution
It provides the most accurate top quark mass measurement to date and combines results from CDF and D0 to establish the current world average.
Findings
Top quark mass measured with less than 1% uncertainty.
Combined results from CDF and D0 improve precision.
Implications for Standard Model Higgs constraints.
Abstract
This letter presents results on the precision measurement of the top quark mass and a combination of the best CDF top mass measurements. A combination by the TevEWWG (Tevatron electroweak working group) of the best top mass results from CDF and D0 in Run 1 and Run 2 of the Tevatron is also presented. This result is the current world average, and offers an uncertainty less than 1%. The new mass value has been included in traditional LEP EWWG fits to precision electroweak data, and implications for the Standard Model Higgs have been derived.
