Regularities in electromagnetic decay widths

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

We revisit Sakurai's remark on the regularities of lepton-pair widths for mesons, extending the panorama to radiative XγγX \to \gamma \gamma and total decays. The regularities persist, and somehow surprisingly some of them seem to relate with Fermi's constant -or Z0Z^0-.
