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 + ',
We re-analyse meson sector data from the CP-PACS collaboration's dynamical simulations [I]. Our analysis uses several different approaches, and compares the standard naive linear fit with the Adelaide Anzatz. We find that setting the scale using the J parameter gives remarkable agreement among data
Radiative and leptonic decays of B-mesons represent an excellent laboratory for the search for New Physics. I present here recent results on radiative and leptonic decays from the Belle and BABAR collaborations.
