Identifying the Next Key Energy Scale for Discovery

Identify the next salient energy or distance scale at which new phenomena beyond the electroweak (∼1 TeV) scale are likely to appear, thereby providing a concrete target for future experimental programs.

Background

The 1‑TeV scale provided a clear target for discovering electroweak symmetry breaking, culminating in the Higgs boson’s discovery. The paper notes that no similarly well‑defined next target scale is currently known.

Determining the next scale would guide strategic choices for future facilities and measurements aimed at unification, dark sectors, flavor, or other beyond‑Standard‑Model physics.
