  The hadronic decays of quarkonium and the B meson inclusive decay into J/Psi
+ X, if treated in the zero-binding approximation, suggest a value of the
strong coupling constant much smaller than the value implied in the standard
model by running from measurements at the Z. Thus, assuming the standard model
is correct in the low energy region, there must be very substantial
relativistic binding corrections to these processes. We discuss the wave
function factor appearing in covariant treatments of quarkonium production and
decay processes with special attention to the way in which the spin of the
quarks carries over into the spin of the bound state. We find that Lorentz
covariance requires that the bound state be a superposition of free quark and
antiquark spinors notably different from the usual ones. We resolve a
superficial apparent paradox suggesting that the relative momentum of the
quarks should lie in a plane perpendicular to the spin quantization axis and we
calculate the J/Psi binding corrections to lepton pair decay and to the
inclusive B decay.
