BCT Letter 22: The QCD Confinement Scale from BCT Vacuum Geometry — Λ_QCD from the D4 Theta-Function Decomposition

  • 1. Independent Researcher

Description

We derive the QCD confinement scale Λ_QCD = 220.44 MeV from BCT vacuum geometry via the D4 theta- function decomposition S_QCD = S_D4(1 − r_tet + α0/2). The result agrees with the PDG value to +0.200% (Prediction #96), using zero free parameters. The BCT programme now counts 96 sub-1% predictions.
