Overview

Physics, Experiments and Detectors (PED)

is one of the main organisational pillars of the FCC project and is responsible for developing the scientific case and the experimental vision for the future collider programme. At CERN, PED is associated with the Research and Computing sector, but its contributors are distributed across universities and institutes in many countries.

PED objectives, scope and deliverables during the FCC-ee Reference Design Phase

The Reference Design Phase establishes the foundations for the FCC-ee experimental programme through:

Continuation of the development of specific conceptual detector designs with the international high-energy physics community
Consolidation of interaction region layouts and detector integration
Background mitigation strategies and machine–detector interface optimisation
Development of a common computing architecture model and finalisation of a common software/analysis framework
Realistic implementation of some of the algorithms needed to confirm the experimental systematic uncertainties on electroweak precision observables
Coordination of the theory community to address the corresponding theory challenges for the FCC-ee
Assessment of the physics case, feasibility, and schedule implications for different centre-of-mass energy stages
Streamlining and optimisation of the procedures for centre-of-mass energy calibration and for possible monochromatic operation at 125 GeV to explore the electron Yukawa coupling
Proposal for staging implementation and improvements of the (staged/descoped) FCC-ee.

These activities are aimed at demonstrating feasibility, integration compatibility and cost realism for the FCC-ee detectors, without committing to a final detector selection or to experiment collaborations forming. Expressions of interest for FCC-ee detectors will be invited after the project approval, with a view to moving towards detector conceptual design reports by 2033.
