Particle physics: recent successes and future prospects

Description: There is no doubt that as yet we do not have an ultimate theory of matter and forces in spite of the remarkable successes of the past decade. In this talk the author attempts to summarize briefly the historical background that led us to the present level of understanding, or more specifically to the standard model of particle physics. Subsequently the author describes several difficulties with this picture, continues with some possible indications of new physics, and finally ends with the discussion of the prospects for the future. 32 references.

Probing the non-minimal Higgs sector at the SSC

Description: Non-minimal Higgs sectors occur in the Standard Model with more than one Higgs doublet, as well as in theories that go beyond the Standard Model. In this report, we discuss how Higgs search strategies must be altered, with respect to the Standard Model approaches, in order to probe the non-minimal Higgs sectors at the SSC.

Physics at the Z/sup 0/

Description: With the next generation of electron-positron colliders on the immediate horizon, we review the standard model and the precision tests of it which can be carried out at the Z/sup 0/ peak. Emphasis is put on the possibilities for discovering new physics, from additional quarks and leptons to extra neutral gauge bosons. 33 refs., 9 figs.

Generation mixing and CP-violation, standard and beyond

Description: We discuss several issues related to the observed generation pattern of quarks and leptons. Among the main topics: Masses, angles and phases and possible relations among them, a possible fourth generation of quarks and leptons, new bounds on neutrino masses, comments on the recently observed mixing in the B - anti B system, CP-violation, and recent proposals for a b-quark ''factory''.

Collider physics for the late 1980's

Description: Topics in the Standard Model of strong and electroweak interactions and how these topics are relevant for the high energy colliders are discussed. Radiative corrections in the Glashow-Weinberg-Salam model are discussed, stressing how these corrections may be measured at LEP and the SLC. CP violation is discussed, followed by a discussion of the Higgs boson and the searches which can be carried out for it. Some features of quantum chromodynamics are discussed which are relevant to hadron colliders. Some of the problems which the Standard Model does not solve are discussed. 115 refs., 53 figs. (LEW)

Supercollider physics

Description: The physics that can be explored with multi-TeV supercolliders is reviewed, including parton distributions, hadron jet production, the standard electroweak theory and minimal extensions to it, technicolor, supersymmetry, and compositeness. 19 refs., 11 figs. (LEW)

Flavor-changing Z/sup 0/ decay

Description: Chapter I reviews the phenomenological situation. Simple estimates of various rates are also provided in order to convey the physical intuition necessary to guide one through the equations and numbers that follow. Chapter II presents technical aspects of the general flavor changing Z/sup 0/ decay calculation, with emphasis on the integration scheme used. Chapter III describes a number of nontrivial checks on the calculation that were performed. Chapter IV contains the entire general algebraic result for the decay rate. Chapter V describes numerical aspects of the computer evaluation, and discusses the parameter values used and the results for the three generation case. A similar presentation for the four generation case is given in Chapter VI. Chapter VII describes what experimentalists should look for in a semiquantitative way. Some possibilities for rate enhancement, and some related processes are mentioned in Chapter VIII.

Prospects for SSC physics

Description: The SSC is primarily designed to explore the physics of the 1 TeV mass scale. Since new heavy particles will decay either into other new particles or into the quanta of the standard model, the main goal of SSC experiments will be to identify and to measure these quanta well. Progress in simulating events and in understanding the signature and backgrounds for standard-model physics is described. 51 refs.
