Measurements of single top-quark production in pp collisions by the CMS experiment

TL;DR

This paper reports on CMS measurements of single top-quark production, including cross sections, CKM matrix element, W-boson helicity, and spin asymmetry, with no deviations from the Standard Model observed.

Contribution

First comprehensive set of CMS measurements of electroweak top-quark production including various properties and couplings, confirming Standard Model predictions.

Findings

Measured production cross sections consistent with Standard Model

Extracted |V_tb| value aligning with CKM matrix expectations

No evidence of anomalous Wtb couplings found

Abstract

A summary of studies of electroweak top-quark production performed by the CMS collaboration is presented. The results include measurements of production cross sections, extraction of the value of $|V_{tb}|$, determination of W-boson helicity in top-quark decays and top-quark spin asymmetry, and a search for anomalous couplings in the Wtb vertex. No deviations from predictions of the standard model are found.
