Book excerpt: During the first year of data taking, the 1999-2000 run, the BABAR detector at the SLAC PEP-II asymmetric collider has collected an integrated luminosity of 20.7 fb[sup -1] corresponding to 22.7 million B[bar B] pairs at the[Upsilon](4S) resonance. Using this data, we present the measurement of sin2[beta] based on samples of B[sup 0][yields] J/[psi] K[sub S][sup 0], B[sup 0][yields][psi](2S) K[sub S][sup 0] and B[sup 0][yields] J/[psi] K[sub L][sup 0] L decays. Our measured value is sin2[beta]= 0.34[+-] 0.20 (stat)[+-] 0.05 (syst). In addition we report on the measurement of branching fractions for exclusive B decays to charmonium final states, measurements of charged and neutral B meson lifetimes and also the B[sup 0][bar B][sup 0] oscillation frequency.
