Running αₛ (QCD) Lab

Live Q probe, n_f overlays, Λ matching to αₛ(M_Z)≈0.118 — asymptotic-freedom toy.

About this tool

Running αₛ (QCD) Lab — one-loop αₛ(Q)=12π/((33−2n_f)ln(Q²/Λ²)). Drag Q and Λ; overlay other n_f; Match Λ so αₛ(M_Z)≈0.118. Optional QED-like contrast curve. Educational toy, not precision QCD.
