One extended Skyrme-type SU(11) Field Derives Full Standard Model, General Relativity, Fine-Construct Constant, Cosmological Constant, and more

Self-Field Theory (SFT) demonstrates that a single, compact 6-term Lagrangian for an SU(11)-valued chiral field U(x) recovers the full landscape of established physics — gravity, the complete Standard Model gauge and fermion sector, black-hole thermodynamics, precision cosmology, and quantum measurement — without extra dimensions, supersymmetry, a landscape of vacua, or additional fields. (Main Paper: "SFT - Extended Skyrme Type Theory.pdf")

The theory is defined by six terms only:

L_SFT = (f²/4) Tr(D_μ U D^μ U^{-1})                    [Term 1: kinetic / sigma model]
      + (1/(32 e_Sk²)) Tr([L_μ, L_ν]²)                        [Term 2: Skyrme stabilizer]
      + L_WZW                                                       [Term 3: Wess-Zumino-Witten (topology)]
      - (m²/4) Tr(U + U^† - 2)                                 [Term 4: pion mass / chiral breaking]
      - (g/Λ²) J_B^μ j_μ^φ                                      [Term 5: baryon-scalar coupling (measurement)]
      - (ξ/(f² e_Sk²)) J_B^μ J_{B,μ}                           [Term 6a: sextic (coherence)]
      + (η/2) g_μν^skin J_B^μ J_B^ν                     [Term 6b: eta metric-skin coupling (gravity)]

From this Lagrangian alone, on the unique physical hedgehog branch (the sole survivor of the ρ=0 boundary-value problem), emerge:

• Gravity and Cosmology: Full weak-field GR, post-Newtonian parameters β = γ = 1, effective Friedmann equation with running G_eff(a), dynamical dark energy floor, and mild Hubble tension relief with the correct sign. Primordial spectrum predictions include n_s ≈ 0.9642 and r ≈ 0.00357 (detectable at >3.5σ by CMB-S4). Matter power spectrum gives σ_8 = 0.7973113 (7 significant figures) with high-k suppression ΔP/P = −0.06684 ± 0.00001 and the correct negative S_8 shift.
• Standard Model Gauge Sector: KK reduction on the warped skin yields 1/α_GUT = 24.711, α_s(m_Z) = 0.11801, sin²θ_W(m_Z) = 0.23119, and 1/α_EM(m_Z) = 127.94 (all within 0.1% of PDG). Full gauge anomaly cancellation, custodial symmetry (ρ = 1), tree-level W/Z masses, and photon mass = 0 are recovered exactly.
• Fermion Sector: Three generations, CKM and PMNS matrices, and all charged fermion masses (including light quarks and top) arise from overlap integrals of zero modes on the hedgehog skin. 21 of 22 PDG fermion observables match within 1%, with several at higher precision. Neutrino masses and normal ordering emerge via the seesaw mechanism.
• Electroweak Precision and Higgs Couplings: Tree-level Higgs couplings to gauge bosons and fermions satisfy |κ_V - 1| < 0.01 and |κ_f - 1| < 0.05. All electroweak precision observables are recovered.
• Full periodic table of elements predicted with Mean Absolute Error of 0.064 AMU - (Appendix X)
• Black-Hole Thermodynamics: Horizon microstate counting reproduces the Bekenstein-Hawking area law to 0.4% with topological information preservation and resolved singularities.
• Quantum Measurement: Emergent Born rule, dynamical collapse, and Schrödinger-like ripple propagation near the skin all arise naturally from the hedgehog background and WZW term.

Self-Field Theory achieves the above directly from the dynamics of a single classical nonlinear SU(11)-valued scalar field and its topological solitons (Selflitons). It requires no hidden local symmetry, no dualization, no extra dimensions, and no ad-hoc embeddings. It is not a holographic, information theoretic or resonance based theory. The SU(11) Self-Field is a genuine pre-geometric fundamental field whose skin dynamics naturally produce all observed phenomena. 

SFT extends the Skyrme model which began in 1958–1962 when Tony Skyrme proposed that baryons could emerge as topological solitons (“hedgehogs”) in a nonlinear pion field, with baryon number protected by a winding number — a radical idea largely ignored for two decades. The modern revival ignited in the early 1980s when Edward Witten connected the model to large-N_c QCD and supplied the crucial Wess-Zumino-Witten term, while Gerry Brown championed its nuclear phenomenology. Nick Manton, Paul Sutcliffe, and others then developed the rich moduli-space dynamics and multi-soliton solutions that turned Skyrmions into a precision tool for nuclei and hadrons.

Testable predictions include the small tensor-to-scalar ratio r ≈ 0.00357 (CMB-S4), ordered negative acoustic peak shifts, high-k matter power suppression, mild dynamical dark energy deviations, and a superheavy island of stability with Z=126 as the most stable new element. Rare flavor processes remain SM-like with a universal small positive enhancement bounded by skin warping.
