Prospects for Colliders and Collider Physics to the 1 PeV Energy Scale

TL;DR

This paper reviews future collider prospects, proposing a plausible scenario to reach 1 PeV energy scale by 2040, emphasizing technical feasibility, costs, and the potential for a new dedicated high-energy physics laboratory.

Contribution

It introduces a detailed, plausible plan for extending collider energy reach to 1 PeV by 2040, including specific collider types and R&D needs.

Findings

A scenario with 5 colliders beyond LHC is feasible within current technical and financial constraints.

Reaching 1 PeV energy scale is possible by early 2040s following historical progress rates.

Most colliders should be housed in a new dedicated high-energy physics laboratory.

Abstract

A review is given of the prospects for future colliders and collider physics at the energy frontier. A proof-of-plausibility scenario is presented for maximizing our progress in elementary particle physics by extending the energy reach of hadron and lepton colliders as quickly and economically as might be technically and financially feasible. The scenario comprises 5 colliders beyond the LHC -- one each of e+e- and hadron colliders and three muon colliders -- and is able to hold to the historical rate of progress in the log-energy reach of hadron and lepton colliders, reaching the 1 PeV constituent mass scale by the early 2040's. The technical and fiscal requirements for the feasibility of the scenario are assessed and relevant long-term R&D projects are identified. Considerations of both cost and logistics seem to strongly favor housing most or all of the colliders in the scenario in a new world high energy physics laboratory
