Regularities in electromagnetic decay widths

Abstract

We revisit Sakurai's remark on the regularities of lepton-pair widths for mesons, extending the panorama to radiative $X\to \gamma \gamma$ and total decays. The regularities persist, and somehow surprisingly some of them seem to relate with Fermi's constant -or $Z^0$-.
