摘要:

在本文中,我们研究了与高能缪子对撞机相关的电弱(EW)修正的几种现象学和技术方面,重点是直接产生过程(无矢量玻色子融合配置)。我们详细研究了达嫩-波兹奥里尼算法的准确性,特别是与精确计算在NLO电弱精度下的比较。我们还评估了在3和10 TeV碰撞中重新求和电弱苏达科夫对数(EWSL)的相关性。此外,我们审查了额外的重玻色子辐射(HBR)的影响,即在包容和半包容配置中弱发射W、Z和希格斯玻色子的影响。所有结果均通过完全自动化的公共代码MadGraph5_aMC@NLO获得。

英文摘要:

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.
