AbstractAbstract
[en] Weak decays of hadrons are examined using the quark theory. Particular attention is paid to the isospin and SU(3) structure and magnitudes of the amplitudes and to dynamical effects of the bound states. Where applicable, the asymptotically free color gauge theory and the MIT bag model are employed. Included in the study are ΔS = 1 decays of baryons and mesons, ΔS = 0 amplitudes that contribute to the parity violating internucleon potential, and predicted ΔC = 1 decays of charmed particles

AbstractAbstract
[en] This talk reviews the mechanisms which can produce the observed CP violation in kaons, and discusses some of the possible future directions for the field. The focus on new directions is important because progress cannot be made until some new form of CP nonconservation is observed

AbstractAbstract
[en] It is likely that in the near future there will be considerable interest in the experimental study of glueballs - bound states of gluons expected in QCD. Such efforts have already begun, primarily at SLAC and at the AGS. While ISABELLE is designed to emphasize other domains of high energy physics, it is possible that there may be open questions that ISABELLE can answer. It is the purpose of this brief note to try to anticipate some of these

AbstractAbstract
[en] One of the beauties of the standard model is the precision with which the masses of the W+- Z0 can be predicted. Radioactive corrections connecting low energy parameters to the pole locations have been done by Marciano and Sirlin, and the masses are predicted to within 2%. The general expectation is that W's and Z0 will be observed as predicted and this has lead to a sense of boredom with this aspect of physics. However, particle theory is presently exploring ideas which may lead to different predictions. It is the purpose of this section to play the devils advocate and describe ways which the standard model may go wrong

AbstractAbstract
[en] I discuss some aspects of the general understanding of masses of the pseudoscalar mesons, and the application of these ideas to the eta' and the tau(1440). A recent calculation of the eta' mass in the bag model is described. It is argued that the characteristics of the tau(1440) favor a glueball interpretation

AbstractAbstract
[en] Given the remarkable successes of the standard model, it is appropriate that books in the field no longer dwell on the development of our current understanding of high-energy physics but rather present the world as we now know it. Dynamics of the Standard Model by Donoghue, Golowich, and Holstein takes just this approach. Instead of showing the confusion of the 60s and 70s, the authors present the enlightenment of the 80s. They start by describing the basic features and structure of the standard model and then concentrate on the techniques whereby the model can be applied to the physical world, connecting the theory to the experimental results that are the source of its success. Because they do not dwell on ancient (pre-1980) history, the authors of this book are able to go into much more depth in describing how the model can be tied to experiment, and much of the information presented has been accessible previously only in journal articles in a highly technical form. Though all of the authors are card-carrying theorists they go out of their way to stress applications and phenomenology and to show the reader how real-life calculations of use to experimentalists are done and can be applied to physical situations: what assumptions are made in doing them and how well they work. This is of great value both to the experimentalist seeking a deeper understanding of how the standard model can be connected to data and to the theorist wanting to see how detailed the phenomenological predictions of the standard model are and how well the model works. Furthermore, the authors constantly go beyond the lowest-order predictions of the standard model to discuss the corrections to it, as well as higher-order processes, some of which are now experimentally accessible and others of which will take well into the decade to uncover

AbstractAbstract
[en] This chapter reviews the structure of glueballs predicted in the MIT bag model, and discusses the present experimental situation and future possibilities. Points out that the bag model has an extensive and reasonably successful experience dealing with quark states which serve to ''normalize'' the methods and parameters; and the gluon fields in the model are Lagrangian fields, massless and gauge invariant. Describes the physical picture of the bag model in analogy to the Meissner effect in superconductivity. Concludes that the bag model has several specific predictions for glueballs: glueballs are light; the spectrum starts with 0++, 2++, 0-+ and 2-+; the G(1440) should be a 0-+ glueball; and a second 2++ state should exist under f(1270)
