- Observation of K* (2060) in the [phi]K[pi] final state produced in proton-nuclei interactions at 400 GeV/cTorres, Sergio (Virginia Polytechnic Institute and State University, 1985)In 1982 Fermilab experiment E623 took data in a search for high-mass boson resonances which decay into one or two ɸ mesons produced in 400 GeV/c proton-nuclei interactions. A hardware trigger selected 3.6 million events with identified K⁺K⁻ pairs. Here I report my study of events with ɸKπ in the final state and present the first evidence for K°*(2060) decaying into ɸKπ and ɸK°*(890).
- Studies of lepton and quark interactionsWang, Ping (Virginia Polytechnic Institute and State University, 1985)Part I Proposed Experimental Tests of the Right-handed Weak Current All possible experiments which test the SU(2)L x U(1)R x U(1)B-L model and SU(2)L x SU(2)R x U(1)B-L model using the LEP e⁺e⁻ collider and HERA e⁻p collider are calculated and the most sensitive experiments are examined. Part II Semi-Phenomenological Theory of (Qq̅) System The (QQ̅) and (Qq̅) mesons are calculated using a QCD motivated potential model. It is discovered that by including a long distance relativistic correction term derived by Grome, the Coulomb + Linear potential works not only for c and b quarks, but s quark as well. The leptonic decay constants of various (Qq̅) mesons together with their masses are predicted. The topponium states are also discussed.
