Karolos Potamianos (for the CDF Collaboration, for the D0, Collaboration)
TL;DR
This paper reviews the latest measurements of the top quark mass at the Tevatron collider, highlighting the precision achieved and its significance for the Standard Model and Higgs boson constraints.
Contribution
It provides a comprehensive summary of the most recent top quark mass measurements using up to 6 fb^{-1} of data from the Tevatron experiments.
Findings
Top quark mass measured at approximately 173.2 GeV/c^2
Uncertainty in the measurement is less than 1 GeV/c^2
Measurements constrain the Standard Model and Higgs boson properties
Abstract
First observed in 1995, the top quark is the third-generation up-type quark of the standard model of particle physics (SM). The CDF and D\O\ collaborations have analyzed many \ttbar\ events produced by the Tevatron collider, studying many properties of the top quark. Among these, the mass of the top quark is a fundamental parameter of the SM, since its value constrains the mass of the yet to be observed Higgs boson. The analyzed events were used to measure the mass of the top quark with an uncertainty of less than . We report on the latest top mass measurements at the Tevatron, using up to of data for each experiment.
