Book Description
The most recent results obtained by the BABAR experiment at the PEP-II asymmetric-energy B Factory at SLAC on CP-violating asymmetries and branching fractions for neutral and charged B decays are presented here. The analysis was performed on a data sample of ≈ 88 million?(4S) → B{bar B} decays collected between 1999 and 2002. Using b → c{bar c}s decays, we measure sin2? = 0.741 ± 0.067(stat) ± 0.034(syst). We also present sin2? measurements from, b → s{bar s}s and b → c{bar c}d processes. From neutral B meson decays to two-body final states of charged pions and kaons, we derive for the CP violating parameters, S{sub??} = 0.02 ± 0.34 ± 0.05 [-0.54, +0.58] and C{sub??} = -0.30 ± 0.25 ± 0.04 [-0.72, +0.12]. First results for B →??−?° and K{sup {+-}}{pi}{sup {-+}}{pi}° final states dominated by the?{sup {+-}} resonance, are also presented.
