Asymptotic Freedom 2D: The Running Strong Coupling α s (Q)

The strong nuclear force is the only fundamental interaction that gets weaker at short distance — a property called asymptotic freedom, discovered by Gross, Politzer and Wilczek and confirmed in every deep-inelastic scattering experiment since the 1970s. This 2D simulator computes the real one-loop QCD beta-function formula for α_s(Q) live as you drag the probe energy Q from 0.35 GeV up to 500 GeV, and renders a stylized proton — three color-charged quarks joined by a gluon flux tube — as a manually-projected 3D arrangement on a single 2D canvas that you can drag to rotate. Tube turbulence, thickness and quark jitter all respond directly to the computed coupling: a tight, rigid, energetic bundle at low Q (confinement) relaxing into a loose cloud of nearly free quarks at high Q. A live α_s vs ln(Q) curve, a live Cornell confinement-potential curve V(r), the β₀ coefficient for your chosen quark-flavor count, and the resolved probe distance r = ħc/Q all update in real time.
