They are confined: no free quarks are observed; the strong coupling grows at low energy (asymptotic freedom at short distance). Established result: see QCD and confinement in the literature; RST maps this via **[[../Relational Friction]]** and **[[../Zoom Logic]]**. ## II. RST/RRT reading | Physics | RST/RRT | |:---|:---| | Confinement | **Relational Friction** — the Format cannot maintain quark-scale distinction against the noise floor (\(\Lambda_{\mathrm{QCD}}\)); resolution fails. | | No free quarks | **Zoom Logic** — coarse-graining: the substrate "sheds" resolution; hadrons are the stable resolution. | | Scale | **typical_scale** → Planck / strong ([[Scale registry]]: quark ~ \(10^{-18}\) m). | ## III. Relations - **composed_of:** — (fundamental in this hierarchy). - **typical_scale:** [[Scale registry]] (quark / strong). - **translates_from:** — (finest in the chain). - **translates_to:** [[Hadron]].
