Abstract

The \it BaBar experiment has recorded the decays of more than 465× 10⁶ BB pairs since 1999, and is reaching an unprecedented precision in the measurement of hadronic B decays. The following results are presented: tests of QCD factorization with the decays B→ χ_c0K^* , B→ χ_c1,2K^(*) , and B⁰→ D^(*)0h⁰, h⁰=π⁰, η, ω, η', study of the decays to charmonium B→ η_c K^(*), η_c(2S) K^(*) and h_cK^(*), measurement of the mass difference between neutral and charged B's, measurement of the "r" parameters for the extraction of the CKM angles sin(2β+γ) with the decays B→ D_s^(*)h, h=π^-, ρ^-, K^(*)+, study of the three-body rare decays B→ J/ψϕK, study of the baryonic decays B⁰→Λ_c⁺p, B^-→Λ_c⁺π^-p, and B^-→Λ_c⁺π⁰p. Except for the published results, all the given numbers are preliminary.
