电子正电子湮没中三喷注产生的电弱修正

Electroweak corrections to three-jet production in electron-positron annihilation

Ansgar Denner, Stefan Dittmaier, Thomas Gehrmann, Christian Kurz

摘要:

本文计算了正负电子对撞机上三喷流产生的电弱${\cal O}(α^3α_s)$修正和相应的事件形状观测量。我们适当地考虑了实验的光子隔离准则和对强子总截面的修正。对三喷流速率和归一化事件形状分布的校正结果是在百分之几的水平上。

英文摘要:

We compute the electroweak ${\cal O}(α^3α_s)$ corrections to three-jet production and related event-shape observables at electron-positron colliders. We properly account for the experimental photon isolation criteria and for the corrections to the total hadronic cross section. Corrections to the three-jet rate and to normalised event-shape distributions turn out to be at the few-per-cent level.
