Cosmin Macesanu, Lynne H. Orr (Rochester)
TL;DR
This paper presents an exact calculation of gluon radiation in top quark production and decay at lepton colliders, analyzing spin correlations, interference effects, and sensitivity to the top decay width.
Contribution
It provides a novel exact calculation including all spin correlations and interferences in gluon radiation during top production and decay at lepton colliders.
Findings
Gluon radiation properties differ between production and decay stages.
Interference effects are sensitive to the top decay width.
The calculation includes all spin correlations and interferences.
Abstract
In this talk we present results of an exact calculation of gluon radiation in top production and decay at lepton colliders, including all spin correlations and interferences. We compare properties of gluons radiated in the production and decay stages and investigate the sensitivity of interference effects to the top decay width.
