Abstract
We review several aspects of the phenomenology of P-wave (q) over bar Q mes ons: mass splittings, effective strong couplings and leptonic constants. We also describe a QCD sum rule determination to order ct, of the form factor tau(1/2)(y) governing the semileptonic B decays to the charm doublet with J(P) = (0(1/2)(+),1(1/2)(+)).
