Available in PDF, EPUB and Kindle. Book excerpt: The BABAR detector at the PEP-II asymmetric B Factory at SLAC collected a sample of 23 x 10[sup 6] B[bar B] pairs in the years 1999 and 2000. Using this data sample, we measure the amplitude of the time-dependent CP-violating asymmetry in neutral B decays to the CP eigenstates J/[psi] K[sub S][sup 0], [psi](2S) K[sub S][sup 0] and J/[psi] K[sub L][sup 0]. We find a value of sin2[beta]= 0.34[+-] 0.20(stat)[+-] 0.05(syst). We also present preliminary measurements of the B[sup 0][bar B][sup 0] oscillation frequency and of the lifetimes of charged and neutral B mesons.
