Result summary

Top quark decays before hadronizing: τ_top≈5×10⁻²⁵s vs τ_QCD≈3×10⁻²⁴s, ratio≈ι_τ/2. Explains why (17/20)ι_τ⁻⁵m_n needs no κ(C;n) correction. The -1449 ppm gap is intrinsic prefactor precision, not missing NLO. All other quarks require confinement corrections.

Reading role

Use as Registry evidence for an existing Results surface.

Claim boundary

This page reports a Registry-backed internal result surface. It is not an external validation claim, a scientific consensus claim, or independent acceptance.

Curation rationale

  • physics-facing terms: qcd
  • candidate is better handled as evidence for an inferred existing public surface

Review notes

  • No additional review notes recorded.
