One-loop electroweak corrections to e+e- into three-jets

TL;DR

This paper calculates the full one-loop electroweak corrections to electron-positron into three-jet processes, assessing their impact on observables relevant for precision measurements.

Contribution

It provides the first comprehensive analysis of electroweak one-loop corrections, including both factorisable and non-factorisable virtual effects, to e+e- into three-jet cross-sections.

Findings

Electroweak corrections significantly affect three-jet observables.

Photon bremsstrahlung impacts the cross-section calculations.

Preliminary results indicate notable electroweak effects on precision measurements.

Abstract

We describe the impact of the full one-loop Electro-Weak terms of O($\alpha_s\alpha^3_{EM}$) entering the electron-positron into three-jet cross-section. We include both factorisable and non-factorisable virtual corrections, photon bremsstrahlung but not the real emission of $W^\pm$ and $Z$ bosons. We show preliminary results and we discuss the impact of the Electro-Weak corrections on three-jet observables.
