摘要

在这项工作中，我们研究了与高能介子对撞机的电弱（EW）校正相关的几个现象学和技术方面，重点是直接产生过程（没有矢量玻色子融合配置）。我们详细研究了Sudakov近似的精度，特别是Denner-Pozzorini算法，并将其与次领先阶EW精度的精确计算进行了比较。我们还评估了在3 TeV和10 TeV碰撞中恢复EW苏达科夫对数的相关性。此外，我们仔细研究了附加重玻色子辐射的影响，即W， Z和希格斯玻色子在包容和半包容构型中的弱发射。所有结果都是通过完全自动化和公开可用的代码adraph5_a@.获得的2025年由美国物理学会出版

EW corrections and heavy boson radiation at a high-energy muon collider

In this work we investigate several phenomenological and technical aspects related to electroweak (EW) corrections at a high-energy muon collider, focusing on direct production processes (no vector-boson-fusion configurations). We study in detail the accuracy of the Sudakov approximation, in particular the Denner-Pozzorini algorithm, comparing it with exact calculations at next-to-leading-order EW accuracy. We also assess the relevance of resumming EW Sudakov logarithms at 3 and 10 TeV collisions. Furthermore, we scrutinize the impact of additional heavy boson radiation, namely the weak emission of W, Z, and Higgs bosons in inclusive and semi-inclusive configurations. All results are obtained via the fully automated and publicly available code adraph5_a@.
