Physics Briefing Book

TL;DR

The Physics Briefing Book summarizes community proposals and discussions to inform the European Particle Physics Strategy Update, guiding future research priorities in European particle physics.

Contribution

It provides a comprehensive overview of the community-driven process for developing the European particle physics strategy, including input collection, review, and synthesis into a strategic document.

Findings

Community proposals for future projects are systematically reviewed.

Discussions inform strategic priorities for European particle physics.

The Briefing Book serves as a foundation for the European Strategy Group's decisions.

Abstract

The European Particle Physics Strategy Update (EPPSU) process takes a bottom-up approach, whereby the community is first invited to submit proposals (also called inputs) for projects that it would like to see realised in the near-term, mid-term and longer-term future. National inputs as well as inputs from National Laboratories are also an important element of the process. All these inputs are then reviewed by the Physics Preparatory Group (PPG), whose role is to organize a Symposium around the submitted ideas and to prepare a community discussion on the importance and merits of the various proposals. The results of these discussions are then concisely summarised in this Briefing Book, prepared by the Conveners, assisted by Scientific Secretaries, and with further contributions provided by the Contributors listed on the title page. This constitutes the basis for the considerations of the European Strategy Group (ESG), consisting of scientific delegates from CERN Member States, Associate Member States, directors of major European laboratories, representatives of various European organizations as well as invitees from outside the European Community. The ESG has the mission to formulate the European Strategy Update for the consideration and approval of the CERN Council.
