abstract
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. 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.

Non-invertible symmetry from the minimal Fibonacci fusion rule forbids tree-level VEVs for multi-Higgs fields H4 and H5, generating them radiatively at one-loop with naturally small values of 10^{-3}-10^{-2} GeV that satisfy the rho parameter.
A z=6.64 Little Red Dot host shows an AGN-driven ionised outflow reaching ~5500 km/s FWHM, with low mass-loading and clear LRD spectral signatures in the compact nucleus.
Six-dimensional primordial black holes with memory burden effects can survive as light dark matter in a two-extra-dimension model at the 10 TeV scale, producing high-multiplicity thermal events at future colliders.
DELIGHT-SHIELD uses a dedicated shield followed by tracking to suppress hadronic and electromagnetic backgrounds by up to seven orders of magnitude, reaching branching ratio sensitivity of O(10^{-9}) for h to phi phi in a dark scalar model.
A resonance- and width-aware parton shower with NLO matching is developed for e+e- to W+W- bbbar, extending beyond standard Breit-Wigner approximations, with a public SHERPA-based simulator.
TQ4Q2.0 supplies the first complete, uncertainty-quantified set of NRQCD-based fragmentation functions for all-heavy tetraquarks, including nonconstituent channels and public grids for jet-associated production.
The OMG3Q1.1 framework delivers the first uncertainty-quantified set of fragmentation functions for all-heavy Ω_{3Q} baryons via diquark-inspired inputs, HF-NRevo evolution, and replica-based error estimation.
A parasitic Compton-backscattering gamma facility at FCC-ee could measure the polarized gluon distribution Δg/g with 1.8–3.0×10^-2 precision at x=0.07–0.19.
Zee models are classified under non-invertible Z_M symmetries; viable candidates are identified from data consistency, and a Z_7 benchmark yields numerical predictions for neutrino parameters and CLFV rates.
Hard final-state radiation measurably destroys the spin entanglement of fermion-antifermion pairs, and the effect should already be visible in LHC ttbar+jet and Belle II tau+tau-gamma data.
Future lepton colliders can improve existing constraints on the tau lepton's dipole moments by several orders of magnitude through complementary channels.
STCF with 1 ab^{-1} can probe several-TeV new-physics scales in sterile-neutrino EFT and constrain an RPV SUSY parameter to ~0.1 TeV^{-2} for apparent BNV in unexplored Lambda_c+ channels.
One-loop corrections in the complex Higgs triplet model shift the 125 GeV Higgs decay rates to WW* and ZZ* upward by a few percent relative to the SM, while allowing up to -20% deviation in gamma gamma and 100% in the self-coupling.
Noncommutative effects up to second order in Θ induce measurable deviations in the e+e− → tt̄ total cross section, polar and azimuthal distributions, and forward-backward asymmetry at ILC and CLIC energies.
Rare charm hadron decays offer clean null tests of the standard model that can reach branching ratios up to 10^{-3} for dark photons and 10^{-4} for ALPs in unconstrained parameter spaces.
Next-to-leading order spurion effects in a minimal lepton flavor deconstruction model induce observable charged lepton flavor violation, lepton flavor universality violation, and electric dipole moments at multi-10 TeV scales.
A multiverse cosmological selection mechanism in an SM extension with scalar singlet and RH neutrinos under B-L dynamically fixes the EW scale while addressing neutrino masses, leptogenesis, and dark matter.
Composite Higgs models with SU(2)_L × SU(2)_R predict spin-1 resonances mixing with electroweak bosons that remain viable at the LHC down to masses of about 1.5 TeV.
Three-loop QCD corrections to electroweak radiative parameters Δρ, Δr, and Δκ are computed, yielding an updated W boson mass prediction relevant for FCC precision targets.
FCC-ee projections indicate at least 10 times better precision on the H to tau tau cross-section than the LHC through ZH and VBF channels plus improved tau reconstruction methods.
Precision Higgs factory measurements can probe composite Higgs models with top quark partners above 3 TeV while also predicting deviations in top-Z couplings.
Silicon tracker PID suppresses backgrounds well for low-momentum b-tagging but requires drift-chamber cluster counting for high-momentum s-jet tagging, with 30 ps timing needed to improve rare b to s decay contamination by an order of magnitude over kinematics alone.
With 6×10^{12} Z bosons at FCC-ee, invisible B-meson branching fractions above 7.6×10^{-9} could be excluded at 90% CL using rectangular cuts and a multiclass BDT on simulated signal and background.
