Future Circular Collider

cern.ch/fcc

What are the smallest

constituents of matter?

?Do supersymmetric particles exist?

What is dark matter?

Open Questions

What are the fundamental laws

that govern nature?

Roads to Discovery

• Higher Energy

– Probe smaller scales

– Discover new particles

• Higher Luminosity

– Detect rare processes

– Measure fundamental parameters

precisely

EC Strategy Update 2013

“CERN should undertake designstudies for accelerator projects in a

global context, with emphasis on

proton-proton and electron-positron

high-energy frontier machines.”

Kickoff Event February ‘14

330 Participants

Conceptual Design Study

• Form global collaboration

• Study pp/ion collider (FCC-hh)

• Infrastructure driven by FCC-hh

• Study e+e- collider (FCC-ee)

• Understand pe option (FCC-he)

Strategic Goals

• Make funding bodies aware of

strategic needs for research community

• Provide sound basis to policy bodies

to establish long-range plans in

European interest

• Strengthen capacity and effectiveness

in high-tech domains

• Provide a basis for long-term

attractiveness of Europe as research area
