M.H.L.S. Wang (for the D0, CDF Collaborations)
TL;DR
This paper reports new top quark mass measurements from the Tevatron, combines them with previous data to update the world average, and discusses implications for the Standard Model, especially Higgs boson constraints.
Contribution
It provides the latest combined top quark mass measurement and explores its impact on Standard Model parameters and Higgs boson mass constraints.
Findings
Updated top quark mass: 170.9±1.1(stat)±1.5(syst) GeV/c²
New constraints on Higgs boson mass
Improved precision in top quark mass measurements
Abstract
New measurements of the top quark mass from the Tevatron are presented. Combined with previous results, they yield a preliminary new world average of Mtop=170.9+-1.1(stat)+-1.5(syst)GeV/c**2 and impose new constraints on the mass of the Higgs boson.
