Meson Supermultiplet Decay Constants

Abstract

We use a covariant supermultiplet theory to determine the primary coupling constant associated with several types of two-body meson decay. Despite the diverse range of decays considered the primary coupling constant is surprisingly uniform. We envisage the extension of the techniques to heavy quark cases, including as preliminary examples the calculation of the $D^{\ast +}$ and $D^{\ast 0}$ total decay widths with results $57.7\pm 1.5$ KeV and $42.5\pm 2.6$ KeV respectively, as well as some predictions about $D^{\ast }$ and $B^{\ast }$ radiative decays.
