[en] The research program of the Duke High Energy Physics Group is described in this Progress Report and a separate Proposal containing their plans for 1994. These two documents are supplemented by compilations of selected publications, thesis abstracts, and the curriculum vitae of the eleven Ph.D. physicists who are carrying out this research program. This Progress Report contains a review of the research which has been done over the first half (1992 and 1993 to date) of the current three-year DOE grant, plus some earlier research to establish a broader perspective of the research interests. High energy physics research at Duke has three components. The first, Task A, is based upon experiments carried out at Fermilab's Tevatron Collider. The group is finishing the analysis of data from their first collider experiment (E735), a study of inclusive particle production from bar p p collisions at √ bar s = 1.8 TeV. The second component of the research, Task B, deals primarily with heavy flavor physics. The third part of the research program, Task D, deals with preparation for research at the SSC. The authors have been active in the development of tracking detectors for the SSC since 1989, and are now concentrating on the design and construction of straw tube drift chambers for the solenoid detector

[en] This Progress Report presents a review of the research done in 1992 by the Duke High Energy Physics Group. This is the first year of a three-year grant which was approved by the Office of High Energy Physics at DOE after an external review of our research program during the summer of 1991. Our research is centered at Fermilab where we are involved with two active experiments, one using the Tevatron collider (CDF, the Collider Detector Facility) and the other using a proton beam in the high intensity laboratory (E771, study of beauty production). In addition to these running experiments we are continuing the analysis of data from experiments E735 (collider search for a quark-gluon plasma), E705 (fixed target study of direct photon and _Χ meson production) and E597 (particle production from hadron-nucleus collisions). Finally, this year has seen an expansion of our involvement with the design of the central tracking detector for the Solenoidal Detector Collaboration (SDC) and an increased role in the governance of the collaboration. Descriptions of these research activities are presented in this report

[en] This progress report presents a review of research done over the past five years by the Duke High Energy Physics Group. This research has been centered at Fermilab where we have had a continuing involvement with both the Tevatron collider and fixed-target programs. In 1988 we began extensive detector R ampersand D for the SSC through its Major Subsystem Program. Duke has been an active member of the Solenoidal Detector Collaboration (SDC) since its formation. These last five years has also been used to finish the analysis of data from a series of hybrid bubble chamber experiments which formed the core of Duke's research program in the early 1980's

[en] A track measuring algorithm has been developed for the RIPPLE bubble chamber film measuring device which is well adapted to the topologies of high energy, high multiplicity events. The algorithm requires the premeasurement of the event vertex and an approximate measurement of the track to determine an inclusive road. The global character permits the accurate measurement of tracks which are obscured over much of their lenght. (orig.)

[en] FNAL E-735 will use a magnetic spectrometer and a central tracking chamber located at the CO intersection area that can utilize low luminosity, from 10/sup 27/ to 10/sup 29/ cm/sup -2/, sec /sup -1/, to measure the transverse momentum distributions dN/dp/sub t/ up to p/sub t/ = 1.4 GeV/c for centrally produced p/sup +-/, K/sup +-/, π/sup +-/ and e/sup +-/ as a function of the charged particle multiplicity n/sub c/. The temperature T and size of centrally produced plasma can be extracted from the transverse momentum (p/sub t/) distributions dN/dp/sub t/ and from the like pion correlations, respectively. Evidence for a quark gluon plasma manifests itself by (a) Breaks in < p/sub t/> as a function of dn/sub c//dy in the central region vertical bar y vertical bar < 3, (b) changes in the particle composition as a function of the charged particle multiplicity n/sub c/. (c) Sudden onset to direct photon and lepton pair production. During the 1987 spring collider run the authors will commission the complete detector system. If commissioning goes well, they will measure the charged particle multiplicity distribution, and the associated transverse momentum distribution
