Quantum Magic and the Strong Coupling Constant

Abstract

The three gauge couplings of the Standard Model (SM) can be parameterized as the fine structure constant $α$, the weak mixing angle $\sin^2θ_w$, and the strong coupling $α_s$. They are fundamental constants whose values remain unexplained. Previously we showed that minimizing magic production in charged-lepton scattering reproduces $\sin^2θ_w$ with great precision. Here we study magic production in the six flavor-diagonal color-singlet channels $q\bar q\to q\bar q$ at tree level, including photon, gluon, $W/Z$, and Higgs exchange. Varying only $α_s$, with all other inputs fixed at each center-of-mass energy, we find that the finite-$α_s$ magic minimum in the top channel reproduces the $\overline{\mathrm{MS}}$ value of $α_s$ to within $5\%$ from $1~$TeV to $10^9~$GeV. Higgs exchange involving the large top Yukawa coupling is essential for this agreement. All six channels produce near-minimal magic at the SM couplings, and reducing $α_s$ toward $α$ increases their magic production, potentially explaining why the strong interaction is ``strong.'' To understand why minimizing magic reproduces both $\sin^2θ_w$ and $α_s$, we conjecture that the parameters of fundamental interactions among color singlets reflect a principle of quantum computational efficiency, with the physical universe emerging from a quantum simulation subject to constrained resources.
