    Multi-GeV Gluonic Mesons

    Lattice QCD gives reliable predictions for hybrid charmonium and multi-GeV glueball masses. Proton-antiproton annihilation may offer an excellent opportunity for the first observation of these states. There are two distinct possible programs: The search for J^PC-exotic and non-J^PC-exotic states. The latter program represents substantially higher cross sections and does not absolutely require partial wave analysis, two very attractive features. The program can be performed with a varying pbar energy <10 GeV and a fixed target.Comment: Invited talk given at The pbar2000 Workshop, Chicago, IL, August 3-5, 2000. 10 pages, LaTe

    Hadron Structure and Modern Spectroscopy

    Get PDF
    The colour, flavour, spin and J^PC of glueballs and hybrid mesons and baryons are constructed in an intuitive manner in both the gluon counting and adiabatic definitions. Glueball decay, production and mixing and hybrid meson decay selection rules and production are clarified.Comment: Invited Lectures at the Advanced School on Quantum Chromodynamics 2000 (QCD2000), Benasque, Huesca, Spain, 3 - 6 July 2000. 26 pages, LaTeX, 4 (encapsulated) postscript figure

    Hybrid Baryon Signatures

    Get PDF
    We discuss whether a low-lying hybrid baryon should be defined as a three quark - gluon bound state or as three quarks moving on an excited adiabatic potential. We show that the latter definition becomes exact, not only for very heavy quarks, but also for specific dynamics. We review the literature on the signatures of hybrid baryons, with specific reference to strong hadronic decays, electromagnetic couplings, diffractive production and production in psi decay.Comment: Talk at ``The Physics of Excited Nucleons'' (NSTAR2000), Newport News, VA, 16-19 Feb. 2000. 8 pages, LaTe

    The Greek Word Porneia in the Matthean Exception Clauses

    Get PDF
    Matthew 5:32 and 19:9 present an interesting exegetical discussion concerning the acceptability and permissibility of divorce. These verses provoke interest because of their inclusion of an exception clause seemingly allowing for a permissible divorce. The verses state the unlawfulness of divorce “except in the case of porneia.” Porneia is the word around which this discussion revolves and its meaning differs vastly depending upon the interpreter. The word is interpreted specifically as adultery during the betrothal period and also as sexual promiscuity and immorality on the other. This thesis explains both views and then seeks to offer all relevant evidence by exploring context, background, lexical meaning, tradition, and the various uses of the word in the New Testament and Septuagint
