Impact of the Recoil Scheme on the Accuracy of Angular-Ordered Parton Showers
Silvia Ferrario Ravasio, Gavin Bewick
TL;DR
This paper investigates how different recoil schemes in Herwig7's angular-ordered parton shower affect the algorithm's accuracy and compares the results with LEP experimental data.
Contribution
It introduces three interpretations of the ordering variable and analyzes their impact on the logarithmic accuracy of the parton shower.
Findings
Different recoil schemes influence the logarithmic accuracy.
Comparisons with LEP data highlight the effects of each scheme.
Recoil scheme choices can improve or degrade simulation precision.
Abstract
In these proceedings we present three possible interpretations of the ordering variable implemented in the Herwig7 angular-ordered parton shower. Each interpretation determines a different recoil-scheme prescription and we show how it can impact the logarithmic accuracy of the algorithm. We also present comparisons with LEP data.
