Book excerpt: This thesis presents studies of CP violation in the decays B0--> K+K-Ks, B+--> K+K-K+, and B+--> KsKsK+, using a Dalitz plot amplitude analysis. These studies are based on data from the BaBar experiment at PEP-II at SLAC. Among the significant results are the world's most precise measurements of time-dependent CP-violation in B0--> phi Ks and direct CP violation in B+--> phi K+. The latter is measured to deviate from zero by 2.8 standard deviations, in tension with the Standard Model expectation. We also study the resonant and nonresonant substructure of B--> KKK decays, and find evidence against the previously hypothesized resonance dubbed the "fX(1500)."
