Abstract
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 VBF configurations). We study in
detail the accuracy of the Sudakov approximation, in particular the
Denner-Pozzorini algorithm, comparing it with exact calculations at NLO EW
accuracy. We also assess the relevance of resumming EW Sudakov logarithms
(EWSL) at 3 and 10 TeV collisions. Furthermore, we scrutinise the impact of
additional Heavy Boson Radiation (HBR), 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 MadGraph5_aMC@NLO.
在这项工作中，我们研究了在高能μ介子对撞机上与电弱（EW）修正相关的几个现象学和技术方面，重点是直接生产过程（无VBF构型）。我们详细研究了苏达科夫近似的精确度，特别是登纳-波佐里尼算法，并将其与 NLO EW 精确度的精确计算结果进行了比较。我们还评估了在 3 TeV 和 10 TeV 对撞中重和 EW 苏达科夫对数（EWSL）的相关性。此外，我们还仔细研究了附加重玻色子辐射（HBR）的影响，即在包容和半包容构型中$W、Z$和希格斯玻色子的弱辐射。所有结果都是通过全自动公开代码 MadGraph5_aMC@NLO 获得的。
