Abstract
A thesis in two independent halves. Part I. A search for the exclusive semileptonic decay modes D^+to| Kpi pi e^+nu_{e} and D^+to| K^{* }pi e^+nu_{e} are presented using data from the Fermi-lab photoproduction experiment E691. With good sensitivity, we observe no signals in the channels D^+to K^ -pi^+pi^circ e^+ nu_{e} and D^+ to| K^circpi^+pi ^- e^+nu_{e}, and set upper limits that represent only a small fraction of the inclusive semileptonic branching ratio. The experiment was conducted at the Fermi-lab Tagged Photon Laboratory, using a large acceptance spectrometer with a silicon microvertex detector to extract a large, clean charm sample. Part II. The physics, design, and results of the Stanford Large Detector (SLD) Cherenkov Ring Imaging Detector (CRID) are described. The physics motivation and performance for the SLD CRID, the principles of Cherenkov detection, and a description of the SLD CRID are combined with a detailed description of the production and testing of the mirrors. In addition, results from the engineering run and cosmic ray tests demonstrate the current status of the system.
