Electroweak Partons at the Muon Collider

by Krzysztof Mekala (University of Warsaw)

Thursday 23 Apr 2026, 11:00 → 12:30 Europe/Rome

Aula A1 (Laboratori Nazionali di Frascati)

Among proposed future projects for particle physics, the Muon Collider has recently attracted significant attention. By combining features of both electron–positron and hadron machines, it offers a potentially powerful environment for exploring high-energy interactions. While technological challenges remain, recent studies suggest none are fundamentally prohibitive, motivating continued research in this direction.

In this talk, I will briefly introduce the Muon Collider in the context of the Update of the European Strategy for Particle Physics and outline the physics opportunities it could offer. I will focus in particular on studies of electroweak interactions at previously unexplored energy scales. After discussing the role of vector boson fusion in this regime, I will review the ideas of the collinear approximation and electroweak factorisation. Finally, I will present the emerging framework of Electroweak Parton Distribution Functions and discuss their relevance for describing high-energy processes.
