Quantum Gravity Full-Scenario Verification: A Joint Detection Scheme for FCC and CMB-S4

This is a preprint of the paper, which has not been peer-reviewed. The final version may be revised based on feedback.Based on the massless graviton Bose-Einstein Condensate quantum gravity framework, this paper proposes a joint detection scheme for the Future Circular Collider (FCC) and the fourth-generation Cosmic Microwave Background experiment (CMB-S4) to achieve full-scenario verification of quantum gravity. At FCC-hh (s=100 TeV), the production cross-sections of 32±1 TeV X bosons and 33±1 TeV Y bosons are predicted to be ~1.2 fb, and that of 71±3 GeV dark matter neutralinos is ~0.5 fb, enabling 5σ detection with 3000fb−1 integrated luminosity. CMB-S4 can capture primordial gravitational waves with a tensor-to-scalar ratio r=0.032±0.002 and discrete oscillation features in the power spectrum (imprinted by dynamic zero-point fluctuations). Explicit falsification thresholds are defined: the framework is invalid if FCC fails to observe 31-34 TeV heavy bosons (σ
