Description
Using heavy quark symmetry we construct an energy sum rule relating the form factor of a heavy flavored meson $ξ(w)$ to the light quark energy distribution. We find that the current available data for $ξ(w)$ is consistent with a broad energy distribution rather than with that of a pure quark/anti-quark bound state, indicating a large nonvalence content.
