Description
Electric dipole moments (EDMs) receive contributions from several CP-violating sources, including effective operators encoding potential physics beyond the Standard Model and the $\theta$ term of Quantum Chromodynamics. Interpreting future EDM measurements, whether null or positive, requires precise hadronic matrix elements of the corresponding renormalized operators. In recent years, the gradient flow has emerged as the most promising tool to tackle these computations, offering a clean and controlled framework for renormalization and operator mixing. In this talk, I will briefly discuss the gradient-flow approach and summarize the current state-of-the-art in non-perturbative calculations of EDM-related matrix elements.
