AGS-787, BNL-Princeton-TRIUMF, began taking data in February 1988 on rare K decays into .pi. and non-interacting neutrals. Recent observations of B-/bar B/ mixing have sharpened the branching ratio prediction of the three generation standard model, (SM), to (approximately) 1-5 x 10−1° for .pi.+.nu./bar /nu//. The detector has 2.pi. acceptance for this decay and 4.pi. acceptance for background gammas. A very large window for viewing new physics exists between the SM value and the previous experimental limit of 1.4 x 10−7. Several other predicted rare K+ decays can be detected. The performance of the detector is described. 8 refs., 4 figs.

Annotation The May-June 1994 conference brought together particle and nuclear physicists to discuss research efforts common to both subdisciplines. These proceedings include plenary and technical papers on topics in CP violation, discrete symmetries, facilities and detectors, hadron dynamics, hadron spectroscopy, hypernuclear physics, leptonic probes of hadronic structure, lepton and meson decays, particle and nuclear astrophysics, and relativistic heavy ion physics. No subject index. Annotation c. by Book News, Inc., Portland, Or.
Includes all works deriving from DOE, other related government-sponsored information and foreign nonnuclear information.
Cities and Their Vital Systems asks basic questions about the longevity, utility, and nature of urban infrastructures; analyzes how they grow, interact, and change; and asks how, when, and at what cost they should be replaced. Among the topics discussed are problems arising from increasing air travel and airport congestion; the adequacy of water supplies and waste treatment; the impact of new technologies on construction; urban real estate values; and the field of "telematics," the combination of computers and telecommunications that makes money machines and national newspapers possible.
