Description

The OJI supported research of J. Ellison has been concentrated in two areas: study of W{gamma} and Z{gamma} production at the Tevatron, which probes the trilinear boson coupling; design, fabrication and testing of silicon microstrip detectors for the D0 upgrade silicon tracking system. The W{gamma} analysis using data from the first D0 run ({approximately}14 pb{sup {minus}1} integrated luminosity) has been completed - J. Ellison and a postdoctoral research working with him (B. Choudhary) were responsible for the muon channel analysis. This analysis is an important test of the Standard Model (SM), since it probes the nature of the WW{gamma} coupling, ... continued below

Description

The OJI supported research of J. Ellison has been concentrated in two areas: study of W{gamma} and Z{gamma} production at the Tevatron, which probes the trilinear boson coupling; design, fabrication and testing of silicon microstrip detectors for the D0 upgrade silicon tracking system. The W{gamma} analysis using data from the first D0 run ({approximately}14 pb{sup {minus}1} integrated luminosity) has been completed - J. Ellison and a postdoctoral research working with him (B. Choudhary) were responsible for the muon channel analysis. This analysis is an important test of the Standard Model (SM), since it probes the nature of the WW{gamma} coupling, which is related to the W boson magnetic dipole and electric quadrupole moments. Any deviation from the SM value of the WW{gamma} coupling would be an indication of either composite structure of the W or higher order loop corrections involving physics beyond the SM. The analysis has resulted in the world`s most sensitive limits on the WW{gamma} coupling parameters. In addition the author has also worked on an analysis of Z{gamma} production which has yielded sensitive limits on the ZZ{gamma} and Z{gamma}{gamma} couplings. The work on the D0 Silicon Tracker has also made very good progress. The team led by J. Ellison includes two postdoctoral researchers (A. Bischoff and C. Boswell), one graduate student (M. Mason) and three undergraduate students. They have fully evaluated proptotype detectors which were designed at UCR and have completed a detailed simulation study of the detector performance for different strip geometries. The results were used to optimize the design of the final D0 detectors, for which UR has sole responsibility. The author has completed the mask design for the 3-chip barrel detectors and production of the final detectors as now begun.
