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 |Vcb| = (42.4 ± 1.2exp ± 2.3thy) × 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.
