AI中文摘要：
标准模型（SM）的三种规范耦合可参数化为精细结构常数α、弱混合角sin²θ_w和强耦合α_s，它们是数值尚未得到解释的基本常数。此前我们已证明，在带电轻子散射中最小化魔力产生量可高精度重现sin²θ_w。本文研究树图水平下六种味对角色单态道q\bar q→q\bar q中的魔力产生，包含光子、胶子、W/Z及希格斯玻色子的交换过程。在每个质心系能量下固定所有其他输入仅改变α_s，我们发现顶夸克道中有限α_s的魔力最小值可在1 TeV至10^9 GeV范围内重现α_s的\bar{MS}值，误差在5%以内，涉及大顶夸克汤川耦合的希格斯交换是该一致性的关键。所有六道在SM耦合下均产生近最小魔力，将α_s向α减小会增加其魔力产生量，这或可解释强相互作用为何“强”。为理解为何最小化魔力可同时重现sin²θ_w和α_s，我们推测色单态间基本相互作用的参数反映了量子计算效率原理，物理宇宙源自受资源约束的量子模拟。
英文摘要：
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.
