WebFeb 27, 2024 · QED is perturbatively renormalizable to all orders due to the BPHZ theorem. However, by a result of Dyson, perturbative expansions in QED are only asymptotic series. One expects that maximum accuracy is gotten by truncating the sum at ∼ 1 α ≈ 137 terms, and that adding more terms will lead the series to diverge.
