【 摘 要 】

Particle physics is the study of the elementary constituents of matter: quarks and leptons. The field also comprises the study of the fundamental interactions, which bind the quarks and leptons into composite particles, allow new particles to be produced, and mediate the decay of unstable particles. The properties of composite particles and the interactions between their constituents can be investigated by studying their production rates, decay characteristics and spectroscopy. In this dissertation, we analyze the weak decay of a heavy quark in a bound state of a quark and antiquark (a meson), focusing on decays in which a bound state of three quarks (a baryon) is produced. The weakly decaying meson that we study is called the B meson because it contains a bottom quark. An abundant sample of B mesons has been produced at the B Factory and recorded by the BABAR detector at the Stanford Linear Accelerator Center (SLAC) located in Menlo Park, CA.
