B decays to excited charm mesons
Abstract
We review several aspects of the phenomenology of P-wave q Q mesons: mass splittings, effective strong couplings and leptonic constants. We also describe a QCD sum rule determination to order αs of the form factor τ1/2(y) governing the semileptonic B decays to the charm doublet with JP=(0+1/2,1+1/2).
