Measurements of Top Properties at the Tevatron

TL;DR

This paper reviews measurements of top quark properties at the Tevatron, including production mechanisms, decay structure, charge, and single-top production, using large datasets from CDF and D0 experiments.

Contribution

It provides comprehensive analyses of top quark properties, testing the consistency of the observed top quark with the Standard Model expectations.

Findings

No evidence of resonant $t\bar{t}$ production.

Confirmation of the V-A structure of the $t\to Wb$ decay.

Constraints on single-top production via flavor-changing neutral currents.

Abstract

The large data samples of thousands of top events collected at the Tevatron experiments CDF and D0 allow for a variety of measurements to analyze the properties of the top quark. Guided by the question "Is the top quark observed at the Tevatron really the top quark of the standard model,'' we present Tevatron analyses studying the top production mechanism including resonant $t\bar{t}$ production, the V-A structure of the $t\to Wb$ decay vertex, the charge of the top quark, and single-top production via flavor-changing neutral currents.
