夏尔巴人电弱Sudakov图的自动评价

Automated evaluation of electroweak Sudakov logarithms in Sherpa

Enrico Bothmann, Davide Napoletano

摘要:

基于[1]中的推导,我们提出了一种自动实现方法,用于计算Sherpa事件生成框架内由电弱辐射校正产生的单回路双Sudakov和单Sudakov时间。在高能量下,这些非线性项构成了对全NLO电弱修正的主要贡献。作为示例,我们展示了大型强子对撞机和未来强子对撞机上相关过程的应用,即壳层W玻色子对的产生、EW诱导的双喷射流的产生以及与四个喷射流相关的电子-正电子的产生,提供了EW修正的第一个估计在这个多重性。

英文摘要:

We present an automated implementation for the calculation of one-loop double and single Sudakov logarithms stemming from electroweak radiative corrections within the Sherpa event generation framework, based on the derivation in[1]. At high energies, these logarithms constitute the leading contributions to the full NLO electroweak corrections. As examples, we show applications for relevant processes at both the LHC and future hadron colliders, namely on-shell W boson pair production, EW-induced dijet production and electron-positron production in association with four jets, providing the first estimate of EW corrections at this multiplicity.
