Unified Fractal Quantum Field Theory (UFQFT) offers a geometric framework in which elementary particles and interactions emerge from resonant structures of energy (Φ) and charge (Ψ) fields in a fractal spacetime with an effective dimension D ≈ 2.70. In this formulation, particle stability, mass hierarchies, and interaction strengths are determined by fluctuations in the fractal dimension (δD), offering a natural explanation for phenomena ranging from quark confinement to neutrino oscillations. The model also predicts and explains the properties of dark matter via a scale-dependent mass spectrum(𝑚 𝐷𝑀 ∼ 𝛬 𝑈𝑉 (3.0 − 𝐷) −1/2), weak-scale interaction cross-sections (𝜎 ∼ (𝐷 − 2.70) 4) and cosmic abundance consistent with 𝛺 DM ≈ 0.26 without fine-tuning. Observable consequences extend to cosmology and high-energy physics, including pronounced cosmic microwave background (CMB) anomalies, collider-accessible fractal excitations, and neutrino spectral perturbations associated with large-scale structure, etc. Schematic visualizations such as Time-Fractal Dimension Evolution and Phase Tree diagrams highlight the combined emergence of quarks, leptons, and gauge branches from an initial fractal symmetry state. Upcoming experiments such as CMB-S4, LiteBIRD, FCC, IceCube, and the Rubin Observatory may provide decisive ways to test these predictions. By unifying dark matter, CMB anomalies, and particle phenomenology within a single fractal-geometric framework, the UFQFT may offer a testable extension beyond the Standard Model and ΛCDM cosmology.
