| Abstract | Future collider facilities are essential to carry out precision measurements in the Higgs sector, perform precision tests of the Standard Model and probe physics beyond it. This document presents a comparative assessment of proposed colliders based on studies in the Physics Briefing Book, focusing on two domains: precision physics – including Higgs physics, electroweak observables, top-quark and flavour physics and strong-interaction studies – and the discovery reach for representative new-physics scenarios. The facilities are evaluated according to their physics potential, energy reach and available centre-of-mass energies. New-physics potential is assessed using benchmark models and a synthesis of direct and indirect sensitivity is made. The methodology and results of the comparisons are summarised. |
