    An amazing coincidence is that the reduced decay rate of J/Psi (the decay rate divided by the cube of its mass) coincides with the one of the pion, which is a spin zero composite. This is an unexplored result.

    As for your original question: understanding of QCD

    Well, I konw we understand QCD better. But could a few specific items be listed, sort of?
