Description
We recently completed a one-loop calculation of the RI/SMOM to $\overline{\text{MS}}$ renormalization scheme conversion factors for the $\Delta S = 1$ four-quark operators with four active quark flavors entirely by prompting an agentic AI system to generate Mathematica code. These are required perturbative inputs for lattice QCD simulations of weak processes such as the RBC/UKQCD calculation of $\Delta M_K$. We discuss our strategy and the methods we used to ensure correctness. We conclude with the prospects for using agentic AI to produce higher-loop results such as the matching factors needed to renormalize bi-local operators and higher-order Wilson coefficients.
