Top-Antitop-Quark Production and Decay Properties at the Tevatron

TL;DR

This paper reviews measurements of top-antitop-quark production and decay at the Tevatron, comparing results to the Standard Model and exploring potential signs of new physics.

Contribution

It summarizes the current experimental status of top-quark properties and searches for physics beyond the Standard Model at the Tevatron.

Findings

Measured top-antitop cross sections agree with Standard Model predictions

No evidence found for new heavy gauge bosons or fourth-generation quarks

Constraints placed on flavor-changing neutral currents

Abstract

At the Tevatron, the collider experiments CDF and DO have data sets at their disposal that comprise a few thousand reconstructed top-antitop-quark pairs and allow for precision measurements of the cross section as well as production and decay properties. Besides comparing the measurements to standard model predictions, these data sets open a window to physics beyond the standard model. Dedicated analyses look for new heavy gauge bosons, fourth generation quarks, and flavor-changing neutral currents. In this mini-review the current status of these measurements is summarized.
