Book Description
Corrections to the naive prediction for the inclusive semihadronic decay rate of the [tau] lepton contain several surprises: electroweak corrections are significant, nonperturbative QCD corrections can be treated systematically, and the order ed /sub s/T perturbative QCD corrections are enormous. The possibility of precise theoretical predictions of the decay rate is discussed. 10 refs.

Book Description
Measurements of hadronic [tau] decays to states containing at least one strange meson are reviewed. New results are presented from a self-consistent analysis of one-prong decays including kaons and from a study of the kaon content in three-prong decays. First observations of the resonance contribution to the strange axial-vector channel are reported. The findings are compared to model predictions of K[sub 1] mixing and interference in [tau] decay.

Book Description
It will soon be the twenty fifth anniversary of the discovery of the tau lepton. It has been an amazing twenty five years for tau physics and for the strong interaction physics that can be deduced from studies of tau decays. The discovery of the tau was based on the elucidation of the nature of about one hundred tau pairs. At this Fifth International Workshop on Tau Lepton Physics new results in tau physics are based on hundreds of thousands or even millions of tau pairs. In the next two decades we will see the data on tau pairs increase by at least a factor of ten. The theoretical work and theoretical understanding of tau physics and tau neutrino physics has also expanded enormously, and this theory will continue to grow in its reach and its depth. Given the vastness of this field and the recognition that there is always great uncertainty in predicting future directions and accomplishments in a scientific field; any perspective of the future of a scientific field is substantially dependent on the author's opinions and guesses. I have limited this talk to seven topics: tau research facilities in the next decades, searching for unexpected tau decay modes, searching for additional tau decay mechanisms, radiative tau decays, tau decay modes of the W, B, and D, searching for CP violation in tau decay, and rethinking the Tau-Charm factory.

Book Description
The II International Workshop on Tau Lepton Physics was held in Ohio, USA in September 1992. Its purpose is to gather the experts on tau lepton physics to examine the current understanding of the tau lepton physics and to assess future prospects. A particular emphasis of the Workshop was a detailed examination of the '1-prong problem': the discrepancy between the inclusive measurement of one-charged-particle decay branching ratio and the sum of the exclusive decays. The Workshop also stimulated new ideas on tests of the Standard Model using the third generation lepton and assessed the future prospects of the lepton physics.

Book Description
Part of the Physics in a New Era series of assessments of the various branches of the field, Elementary-Particle Physics reviews progress in the field over the past 10 years and recommends actions needed to address the key questions that remain unanswered. It explains in simple terms the present picture of how matter is constructed. As physicists have probed ever deeper into the structure of matter, they have begun to explore one of the most fundamental questions that one can ask about the universe: What gives matter its mass? A new international accelerator to be built at the European laboratory CERN will begin to explore some of the mechanisms proposed to give matter its heft. The committee recommends full U.S. participation in this project as well as various other experiments and studies to be carried out now and in the longer term.
