| Description | Speaker: Jens Osterhoff (LBL) Title: Wakefield Accelerator Colliders for Particle Physics Room: 285 Host: Matthew Citron Abstract: Since its inception, the field of advanced accelerator research has regarded future particle-physics colliders as the ultimate application of >1 GV/m accelerator technology. Over the last decades, great experimental and theoretical progress [1,2,3] has enabled and motivated new concepts for potential future colliders based on wakefield accelerators (WFAs), both for Higgs factories and at the energy frontier. The most recent P5 Report [4] calls for “vigorous R&D toward a cost-effective 10 TeV pCM collider based on proton, muon, or possible wakefield technologies.” Specifically, the P5 Report requests “the delivery of an end-to-end design concept, including cost scales, with self-consistent parameters throughout” for a WFA machine. This presentation will outline the plan to produce such a design, and the opportunities and challenges for wakefield-based colliders, both as standalone machines and as a future technology upgrade option. WFA colliders at the energy frontier will likely operate in a new regime characterized by beam-beam interactions with large quantum beamstrahlung effects. Preliminary studies of the physics case in this regime at 10 TeV will be presented. [1] C. A. Lindstrøm et al. “Beam-driven plasma-wakefield acceleration”, arXiv:2504.05558 (2025) [2] E.
