Book excerpt: The decays D° → ?/sup −/e?/sub e/ and D° → K/sup −/e+?/sub e/ are observed in a sample of e+e/sup /minus// → ?(3770) events collected with the Mark III detector at SPEAR. The branching fractions B(D° → ?/sup /minus//e+?/sub e/) = (0.39/sub /minus/0.11//sup +0.23//plus minus/0.04)% and B(D° → K/sup /minus//e+?/sub e/) = (3.4/plus minus/0.5/plus minus/0.4)% are measured. The ratio of Kobayashi-Maskawa matrix elements V/sub cd//V/sub cs/ 2 = (0.057/sub /minus/0.015//sup +0.0.38//plus minus/0.005) is obtained under the assumption that the form factors f/sub +//sup K/(0) and f/sub +//sup ?/ are equal. A study of the absolute D/sub s//sup +/ hadronic branching fractions is made by searching for fully reconstructed e/sup +/e/sup /minus// /yields/ D/sub s//sup */plus minus//D/sub s//sup /minus plus// events at /radical/s = 4.14 GeV.

Book excerpt: We report recent results on charmed meson decays, obtained using the Mark III detector at SPEAR. The first topic discussed is the observation of ee− .-->. D/sub s/D/sub s/* at .sqrt.s = 4.14 GeV. The D/sub s/* is detected as a peak in the mass distribution recoiling from D/sub s//sup + -/ .-->. phi.pi./sup + -/. The mass of the D/sub s/* is found to be (2109.3 +- 2.1 +- 3.1)MeV/c2, yielding a D/sub s/*-D/sub s/ mass difference of (137.9 +- 2.1 +- 4.3) MeV/c2. The production cross section times branching ratio is also measured. Next, a search for the decay D .-->. .mu.+nu/sub .mu./ is described. A preliminary upper limit (90% CL) on B(D+ .-->. .mu.+nu/sub .mu./) of 8.4 x 10−4 is obtained, corresponding to an upper limit on the decay constant f/sub D/ of 340 MeV/c2. Finally, we present results of a search for the lepton family number violating decay D° .-->. .mu.e. We find B(D° .-->. .mu.e)

Download or read book Research Directions For The Decade (Snowmass 1990) - Proceedings Of The 1990 Summer Study On High Energy Physics written by Berger Edmond L and published by World Scientific. This book was released on 1992-09-16 with total page 828 pages. Available in PDF, EPUB and Kindle. Book excerpt: With the advent of the Superconducting Super Collider and other new technologies, coupled with the development of particle astrophysics and other non-accelerator based physics, research in high energy particle physics in the nineties promises to break into new and exciting frontiers. To chart the directions and opportunities for this new decade, the 1990 Summer Study on High Energy Physics was organized in Snowmass, Colorado. Like previous Snowmass Summer Studies, it plays a key role in shaping research directions and in drawing the particle physics community together.This book of the proceedings examines the full spectrum of important scientific issues and opportunities in high energy particle physics in the decade of the 1990's, including research at existing and anitcipated hadron-hadron, e+e-, and ep colliders; research at fixed-target facilities; the scientific potential of possible new facilities such as B factories; particle astrophysics and non-accelerator based physics; and accelerator and detector initiatives. It also discusses the physics and technical aspects of the initial Superconducting Super Collider experimental program.This volume, therefore, offers a captivating glimpse into the future of high energy physics, and makes essential reading for all physicists interested in assessing the exciting new research opportunities the future technologies would bring.

Download or read book Cities and Their Vital Systems written by Advisory Committee on Technology and Society and published by National Academies Press. This book was released on 1989 with total page 1298 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book B Decays written by Sheldon Stone and published by World Scientific. This book was released on 1994 with total page 676 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 2nd edition is an extensive update of "B Decays?. The revisions are necessary because of the extensive amount of new data and new theoretical ideas. This book reviews what is known about b-quark decays and also looks at what can be learned in the future.The importance of this research area is increasing, as evidenced by the approval of the luminosity upgrade for CESR and the asymmetric B factories at SLAC and KEK, and the possibility of experiments at hadron colliders.The key experimental observations made thus far, measurement of the lifetimes of the different B species, B0-B0 mixing, the discovery of ?Penguin? mediated decays, and the extraction of the CKM matrix elements Vub and Vcb from semileptonic decays, as well as more mundane results, are described in great detail by the experimentalists who have been closely involved with making the measurements. Theoretical progress in understanding b-quark decays using HQET and lattice gauge techniques are described by theorists who have developed and used these techniques.Synthesizing the experimental and theoretical information, several articles discuss the implications for the ?Standard Model? and how further tests can be done using measurements of CP violation in the B system.
