Calculation of exclusive decay modes of the tau.
We update the calculation of the decays of the tau lepton into various modes using recent data on electron-positron annihilation into hadrons plus bounds that follow from isotopic-spin conservation. Comparison is made with exclusive branching-ratio data and inclusive charged-prong-distribution measurements in tau decays, and the difficulty in accounting for all the one-charged-prong decays as a sum of exclusive decay modes is discussed.

title: Symmetry Predictions from Sum Rules without Saturation
abstract: The application of sum rules derived from current commutation relations to give $\mathrm{SU}(6)$-like results is developed without the assumption of saturation. We first derive a consistency condition by comparing sum rules, and then study the sum rules for $\frac{1}{g_{A}^{}{}_{}{}^{2}}$ and the isovector charge radii, replacing the assumption of saturation with a simple dynamical model for the remaining continuuum contribution. This results in several $\mathrm{SU}(6)$-like predictions which contain important correction factors to the results previously derived assuming saturation. We have also re-examined the experimental data for the sum rule for $\frac{{〈r_{N}^{}{}_{}{}^{2}〉}^{V}}{6}$, and find that it converges below 1 GeV like the sum rule for $\frac{1}{g_{A}^{}{}_{}{}^{2}}$ when account is taken of the contribution to the sum rule of the large resonant ${M}_{1+}$ and nonresonant ${\mathrm{E}}_{0+}$ multipoles in pion photoproduction, and of the ${N}^{**}(1520)$.

title: CP violation in K decays
abstract: As in the case for much of contemporary research in high energy physics, the area of CP (the product of charge conjugation and parity) violation in K decays is to be seen in the context of a much broader effort of looking for physics beyond the Standard Model. One of the specific types of such physics is represented by the possibility of a fourth family, as exemplified by the title and main focus of this conference. From the broader perspective of looking for new physics of any kind, there are two principal avenues:

title: Forward-angle charged-pion electroproduction in the deuteron.
abstract: A direct experimental determination has been made of the ratio of the forward-angle positive-pion electroproduction cross section for a proton bound in the deuteron with that of a free proton for invariant masses of 1160 and 1232 MeV. A significant quenching of the reaction in the deuteron is observed.

title: Measurement of tensor polarization in elastic electron-deuteron scattering at large momentum transfer
abstract: Tensor polarization observables ( t(20), t(21), and t(22)) have been measured in elastic electron-deuteron scattering for six values of momentum transfer between 0.66 and 1.7 (GeV/c)(2). The experiment was performed at the Jefferson Laboratory in Hall C using the electron High Momentum Spectrometer, a specially designed deuteron magnetic channel and the recoil deuteron polarimeter POLDER. The new data determine to much larger Q2 the deuteron charge form factors G(C) and G(Q). They are in good agreement with relativistic calculations and disagree with perturbative QCD predictions.

title: Neutron and proton matrix elements for 21+ transitions in T=1 nuclei from pion inelastic scattering.
abstract: Cross sections have been measured for ..pi../sup +/ and ..pi../sup -/ inelastic scattering to the 2/sub 1//sup +/ levels of /sup 18/O, /sup 22/Ne, /sup 26/Mg, /sup 30/Si, and /sup 34/S. The data are used to infer neutron and proton quadrupole-matrix elements for these transitions. The matrix elements extracted from the pion data are in good agreement with their corresponding electromagnetic matrix elements. These results indicate that the use of the distorted-wave impulse-approximation is a valid procedure for this class of transition.

title: Distribution of proton spectroscopic strengths in the odd-A Rb isotopes.
abstract: The /sup 78,80,82/Kr(/sup 3/He,d) reactions have been used to measure proton spectroscopic factors for many low-lying levels in /sup 79,81,83/Rb. Summed spectroscopic strengths and the distributions of strength among states are compared to recent theoretical predictions. The spreading of strength is found to be less than predicted, especially for the 2p/sub 1/2/ and 1g/sub 9/2/ orbitals.

title: Measurement of tensor analyzing power in electron-deuteron elastic scattering.
abstract: An internal-target technique was used to make the first measurements of the tensor analyzing power {ital T}{sub 20} of electron-deuteron elastic scattering in the four-momentum-transfer range of 2--3 fm{sup {minus}1}. Polarized deuterium atoms were confined within a storage cell in the VEPP-3 electron storage ring in Novosibirsk to achieve a total target thickness of 3{times}10{sup 12} cm{sup , 15 times greater than was previously possible with an atomic-beam target alone. The results for {ital T}{sub 20} are in agreement with reasonable models of the deuteron wave function.
