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.
