Book Description
Limits at the 10−4 level are reported for rare and forbidden decays of the D° charm meson to a pair of leptons and either a vector meson or two pseudoscalar mesons. Of these searches, 18 are investigations of decays without previous published results; several others have significantly improved sensitivity over previous results.

Book Description
We report the results of a blind search for flavor-changing neutral current (FCNC), lepton-flavor violating, and lepton-number violating decays of D, D{sub s}, and D° mesons (and their antiparticles) into 2-, 3-, and 4-body states including a lepton pair. Such decays may involve Flavor-Changing Neutral Currents, Leptoquarks, Horizontal Gauge Bosons, or Majorana Neutrinos. No evidence for any of these decays is found. Therefore, we present 90% confidence level branching-fraction upper limits, typically at the 10−4 level. A total of 51 decay channels have been examined; 26 have not been previously reported and 18 are significant improvements over previous results.

Pages : 105
Book Description
I report the results of a search for flavor-changing neutral current, leptonflavor, and lepton-number violating decays of the 3 and 4-body decay modes of the D0 (and its antiparticle) containing muons and electrons. Using data from Fermilab charm hadroproduction experiment E791, I examine modes with two leptons and either a [rho]0, $\bar{K}$0, or [Phi] vector meson or a non-resonant [pi][pi], K[pi], or KK pair of pseudoscalar mesons. No evidence for any of these decays is found. Therefore, branching-fraction upper limits, typically at the 10-4 level, are presented at the 90% confidence level for the 27 decay modes examined. Of these searches, 18 are investigations of decays without previous published results; several others have significantly improved sensitivity over previous results.

Heavy Quarks at Fixed Target
Author: Harry W.K. Cheung
Publisher: American Institute of Physics
ISBN:
Category : Medical
Languages : en
Pages : 556
Book Description
This conference provided a comprehensive overview of the areas where fixed target experiments made significant contributions so that experimenters could see what work was left to be done. Since experiments at colliders contribute strongly in many of these areas, the participation of collider experimenters was welcomed and this edition of the conference contains many contributions from the collider community. In order to try to cover the huge amount of physics included in studies of heavy quarks, many of the contributions are review types, including both theoretical and experimental overviews in seven different areas: CP violation and mixing; heavy ions; production dynamics and structure functions; hadronic decays; semileptonic and leptonic decays; spectroscopy; and rare and forbidden decays. This volume is divided into these seven areas of interest.

Environmental Aspects of Zoonotic Diseases
Author: Robert Armon
Publisher: IWA Publishing
ISBN: 184339085X
Category : Science
Languages : en
Pages : 517
Book Description
Environmental Aspects of Zoonotic Diseases provides a definitive description, commentary and research needs of environmental aspects related to zoonotic diseases. There are many interrelated connections between the environment and zoonotic diseases such as: water, soil, air and agriculture. The book presents investigations of these connections, with specific reference to environmental processes such as: deforestation, floods, draughts, irrigation practices, soil transfer and their impact on bacterial, viral, fungal, and parasitological spread. Environmental aspects such as climate (tropical, sub-tropical, temperate, arid and semi-arid), developed and undeveloped countries, animal (domestic and wild) traffic animal border crossing, commercial animal trade, transportation, as well geography and weather on zoonosis, are also discussed and relevant scientific data is condensed and organized in order to give a better picture of interrelationship between the environment and current spread of zoonotic diseases. Altogether, the book presents a remarkable and a vast amount of potential future research directions based on the link: environment-vectors-pathogens-humans. The most up-to-date source of information on this increasingly important cross-disciplinary subject, Environmental Aspects of Zoonotic Diseases will be invaluable for environmentalists, veterinarians, medical staff, environmental engineers, government agencies and consultants working in this field.
