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 + ',
Thanks to excellent luminosity of the KEKB e + e -asymmetric collider, several new resonances with "hidden charm" have been observed in B meson decays by the Belle experiment. In this report, two resonances of X(3872) and Y (3940) which were found in B decays, are described.
