High transverse momentum at Isabelle

The present data on high P/sub T/ hadronic phenomena are summarized. Inclusive pion production, quantum numbers, and jet structure are included. (JFP

Electromagnetic and weak interactions at Isabelle

A survey is given of the present status and expectations for studying mu /sup plus or minus and W/sup plus or minus production in pp interactions using the Isa belle muon detector. A brief description is given of the experimental arrangement. Some predictions based on the DrellYan parton-- antiparton annihilation model and the modified Drell-Yan model are discussed. (LBS

HyperCP: A high-rate spectrometer for the study of charged hyperon and kaon decays

The HyperCP experiment (Fermilab E871) was designed to search for rare phenomena in the decays of charged strange particles, in particular CP violation in $\Xi$ and $\Lambda$ hyperon decays with a sensitivity of $10^{-4}$. Intense charged secondary beams were produced by 800 GeV/c protons and momentum-selected by a magnetic channel. Decay products were detected in a large-acceptance, high-rate magnetic spectrometer using multiwire proportional chambers, trigger hodoscopes, a hadronic calorimeter, and a muon-detection system. Nearly identical acceptances and efficiencies for hyperons and antihyperons decaying within an evacuated volume were achieved by reversing the polarities of the channel and spectrometer magnets. A high-rate data-acquisition system enabled 231 billion events to be recorded in twelve months of data-taking.Comment: 107 pages, 45 Postscript figures, 14 tables, Elsevier LaTeX, submitted to Nucl.

Task D, Participation in high energy physics

This grant was initiated in December of 1989. My request for DOE funds (July 7, 1989) listed three activities which would require support from DOE. These were communication of HEP and Basic Research activities via lectures, articles, TV, etc., science education activities and participation in E789, a fixed-target research on beauty physics at Fermilab. These activities are discussed in this report

Participation in high energy physics, Task D

This report discusses the following topics: Communication and Advancement of High Energy Physics; B-Quarks; Secondary Vertex Trigger; and Science Education

The Fermilab upgrade

This paper discusses the upgrades needed at Fermilab Tevatron facility to meet the future physics needs. Historical aspects are also discussed. 3 figs

A one-campus SSC

Advantages of the one-campus superconducting super collider with bypass-clustered Interaction Region arrangement are enumerated. Designs for double-bypass arrangements with 4 and 6 interaction points are examined and presented. Compared to the conceptual design given in the Conceptual Design Report, the only drawback identified is the additional dipoles required which amounts to approx.20% for the 6 Interaction Point arrangements and approx.10% for the 4 Interaction Point arrangements.

An Evaluation of the Legibility and Meaningfulness of Potential Map Symbols

The legibility and meaningfulness of a series of point and linear symbols were evaluated for potential use on tactual maps representing building interiors. The representations included symbols developed by other researchers as well as a number designed specifically for this study. A subset of “optimally sized” symbols, including the different representations of women's washroom, men's washroom, telephone, and stop/danger sign, were tested for legibility, and the meaningfulness of this subset of symbols was then evaluated. Blind observers were used. The findings are discussed in terms of which symbols would best represent the four environmental features.</jats:p
