Whether the ESPPU will include concrete strategy for beyond‑collider projects

Ascertain whether the European Strategy for Particle Physics Update will present a concrete, united strategy for beyond‑collider particle physics comparable to its strategy for the next flagship collider, and specify the scope of such recommendations.

Background

The authors note that the ESPPU is expected to provide a concrete, united European strategy for the next flagship collider project, which will guide national and international funding agencies. However, they explicitly state uncertainty about whether a similar level of strategic guidance will be provided for beyond‑collider particle physics.

This uncertainty matters because the paper argues that beyond‑collider experiments are integral to the European particle physics landscape and would benefit from concrete recommendations to sustain and grow the field. Clarifying the ESPPU’s scope would help institutions and funding agencies plan accordingly.
