Electroweak Cross-sections and Widths

TL;DR

This paper reviews recent measurements of W and Z boson production cross-sections and widths from the CDF and D0 experiments, highlighting new results in tau decay channels, kinematic distributions, and width determinations.

Contribution

It provides an updated overview of experimental measurements of electroweak boson properties, including novel results on Z to tau pairs and direct W width measurements.

Findings

Measured Z production cross-section times tau decay branching ratio.

Analyzed Z rapidity and transverse momentum distributions in electron channel.

Performed direct measurements of W width and Z invisible width.

Abstract

The status of W and Z cross-section and width measurements from the CDF and D0 experiments is reviewed. Recent results that are discussed: the cross-section for Z production times the branching ratio to tau pairs, the rapidity and transverse momentum distributions of Z production in the electron channel, and the direct measurements of the W width and the Z invisible width; the latter from an analysis of events with large missing transverse energy and one or more energetic jets.
