Abstract

The interplay of experiment and theory is explored in the context of current data on b and c decay. Measurements of |V_cb| and |V_ub| are extracted from existing data. Conservative estimates give |Vcb| = (42.4 ± 1.2_exp ± 2.3_thy) × 10⁻³ and |V_ub|=(3.90± 0.16_exp± 0.53_thy) × 10^–3. Using these values along with data on B_d, B_s mixing and CP violation in the K_L 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 D_sJ states, discovered by BaBar and CLEO, respectively, are interpreted in light of the observation of these states in B decays by Belle. PACS: 13.25.Hw Decays of bottom mesons – 13.20.Fc
