Effective Field Theory for Top and Weak Boson Physics

TL;DR

This paper discusses the application of effective field theory to top quark and weak boson physics, including tree-level and one-loop processes, and addresses unitarity concerns at high energies.

Contribution

It introduces the use of effective field theory for analyzing top and weak boson interactions, emphasizing its applicability beyond unitarity bounds.

Findings

Effective field theory effectively describes top and weak boson properties.

Application to weak boson pair production demonstrates the framework's utility.

Unitarity bounds are not a concern within the energy range of current data.

Abstract

Effective field theory is the ideal framework for discussing top and weak boson properties. We discuss the application of this framework to top physics at both tree level and one loop. We consider weak boson pair production within an effective field theory framework, and argue that one need not be concerned with the violation of unitarity bounds at energies beyond the region where there are data.
