Sum Rule for Heavy Meson Decay Widths

Abstract
A sum rule relating the widths of the decays of mesons belonging to heavy quark multiplets, having the same parity and light quark spin j, into the low lying and multiplet is obtained. As this sum rule follows from properties of the axial charges, it is protected from heavy quark spin dependent corrections. The sum rule works well for mesons containing a heavy charmed quark and, surprisingly, for resonances containing a strange quark.
