Abstract

The interplay of experiment and theory is explored in the context of current data on b and c decay. Measurements of |Vcb| and |Vub| are extracted from existing data. Conservative estimates give \(\left|V_{cb}\right|=(42.4\pm 1.2_{exp} \pm 2.3_{thy})\times 10^{-3}\) and |Vub|=(3.90± 0.16exp± 0.53thy) × 10–3. Using these values along with data on Bd, Bs mixing and CP violation in the KL system, the allowed region of the CKM parameters ρ and η is derived. Tests of factorization in two-body hadronic B decays to one heavy and one light meson are shown and compared with modern theories which are also used to see if there is new physics in two-body B decays to light mesons. The two new narrow DsJ states, discovered by BaBar and CLEO, respectively, are interpreted in light of the observation of these states in B decays by Belle.
