✦ Synopsis

We review several aspects of the phenomenology of P-wave ~Q mesons: mass splittings, effective strong couplings and leptonic constants. We also describe a QCD sum rule determination to order c~s of the form factor T1/2(y) governing the semileptonic B decays to the charm doublet with jR = (0 + 1 + ', 1/2 ~ i/2/'
