A class of meson decay modes sensitive to only one quark topology at leading (Formula presented) order (annihilation of valence quarks through a (Formula presented) is described. No experimental observations, or even upper limits, have been reported for these decays. This work presents a simpleminded (order-of-magnitude) calculation of their branching fractions, and compares to results of previous calculations where available. Although rare, one of these modes (Formula presented) might already be observable at charm experiments; two others (Formula presented) (Formula presented) should appear at the B factories, and the rest at hadron colliders.
