The impending update to the European Strategy for Particle Physics is an apt moment to chart the future of the field — a future that should be supported and ensured.
European Strategy for Particle Physics
The European Strategy for Particle Physics is the decision-making process underpinning the long-term future of particle physics in Europe. This Focus issue outlines the main proposals under consideration for the 2020 update to the strategy.
The particle physics community refreshes the roadmap for the field in Europe, taking into account the worldwide context, in the so-called European Strategy for Particle Physics update, which happens every seven years.
The Future Circular Colliders are proposed as a future step after the Large Hadron Collider has stopped running. The first stage foresees collision of electron–positron pairs before a machine upgrade to allow proton–proton operation.
The Compact Linear Collider is a proposed high-luminosity electron–positron collider that can reach TeV-scale energies. Its accelerator design and physics programme, mainly focusing on precision measurements and new physics searches, are discussed.
Within the Physics Beyond Collider programme, complementary methods to high-energy frontier particle colliders to investigate the physics of elementary particles and their interactions are studied.
Proposals for the particle physics programmes in the United States and Asia are discussed; mainly the International Linear Collider in Japan, the Circular Electron–Positron Collider in China and accelerator-based long-baseline neutrino experiments in the United States.
