Volume 1 of the FCC Feasibility Report presents an overview of the
physics case, experimental programme, and detector concepts for the
Future Circular Collider (FCC). This volume outlines how FCC would
address some of the most profound open questions in particle physics,
from precision studies of the Higgs and EW bosons and of the top quark,
to the exploration of physics beyond the Standard Model. The report
reviews the experimental opportunities offered by the staged
implementation of FCC, beginning with an electron-positron collider
(FCC-ee), operating at several centre-of-mass energies, followed by a
hadron collider (FCC-hh). Benchmark examples are given of the expected
physics performance, in terms of precision and sensitivity to new
phenomena, of each collider stage. Detector requirements and conceptual
designs for FCC-ee experiments are discussed, as are the specific
demands that the physics programme imposes on the accelerator in the
domains of the calibration of the collision energy, and the interface
region between the accelerator and the detector. The report also
highlights advances in detector, software and computing technologies, as
well as the theoretical tools/reconstruction techniques that will
enable the precision measurements and discovery potential of the FCC
experimental programme. The content and structure of this report are
guided by the scope and priorities defined in the mandate of the FCC
Feasibility Study. It is therefore not intended to serve as an
exhaustive review of the full physics potential of FCC. Several topics,
already covered in earlier reports such as the FCC CDR, are not
reiterated here or are addressed only briefly, in alignment with the
study’s focus. This volume reflects the outcome of a global
collaborative effort involving hundreds of scientists and institutions,
aided by a dedicated community-building coordination, and provides a
targeted assessment of the scientific opportunities and experimental
foundations of the FCC programme.
