Synopsis Bose-Einstein Correlations of Pions in Ee− Annihilation at 29 GeV Center-of-mass Energy by :
Measurements of two- and three-particle correlations between like-sign pions produced in ee− annihilation at 29 GeV center-of-mass energy are presented. The analysis is based on data taken during the period 1982--1986 using the TPC/2.gamma. detector at PEP. Two-particle correlations are studied as a function of Q, the momentum difference as measured in the rest frame of the pion pair, and as a function of q0, the energy difference as measured in the lab frame. The Bose-Einstein enhancement is observed when Q is small even when the energy difference, q0, is substantial. This observation provides evidence that the Bose-Einstein correlations are best described by a model that correctly accounts for the relativistic motion of the particle sources. Three-pion correlations are measured both by using a standard three-pion correlation function, and also by using a correlation function for which the correlations between the pairs of pions within the triplet have been subtracted. The observation of three-pion correlations after pair correlations have been subtracted supports the interpretation that the observed correlations are due to Bose-Einstein interference. 56 refs.

Synopsis Inclusive Hadron Production and Two Particle Correlations in Ee− Annihilation at 29 GeV Center-of-mass Energy by :
We have studied hadron production in ee− annihilation at 29 GeV center-of-mass energy using the PEP-4 Time Projection Chamber Detector. The inclusive cross sections and mean multiplicities for .pi./sup + -/, K/sup + -/ and (p + anti p) production have been measured using ionization energy loss to separate particle species. We find on average 10.7 +- 0.6 .pi./sup + -/, 1.35 +- 13 K/sup + -/ and 0.60 +- 0.08 (p + anti p) per multihadron event. The differential cross section is well described by a number of Monte Carlo hadronization models. In addition, we have observed correlations in rapidity space for identified pions and kaons. Short-range KK correlations provide evidence for local flavor compensation during hadronization. Long-range .pi pi. and KK correlations indicate that the initial partons carry flavor. We also observe significant long-range .pi. K correlations as a result of heavy quark decays. 85 references, 67 figures, 11 tables.

Synopsis Image and Logic by : Peter Galison
Engages with the impact of modern technology on experimental physicists. This study reveals how the increasing scale and complexity of apparatus has distanced physicists from the very science which drew them into experimenting, and has fragmented microphysics into different technical traditions.

Synopsis Mass Identified Particle Production and Bose Einstein Correlations at 1800 GeV. by :
Results were shown on transverse momentum distributions of [pi], k and p from Fermilab experiment E735. This experiment, related to the search for quark gluon plasma, was run at the Fermilab Tevatron collider with {bar p}p collisions at √s = 1800 GeV. Dependence of particle ratios on transverse momentum and center of mass energies was shown. Results were also shown on Bose Einstein correlations between pairs of identical pions and a measure of size and lifetime of the source.

Synopsis Bose-Einstein Correlations in 14. 6 Ater Dot GeV by :
The E802 spectrometer at the Brookhaven AGS has been used to obtain two-particle inclusive pion distributions from E/A = 14.6 GeV 28Si + 197Au and 27Al interactions. Data are presented for pions near center-of-mass rapidity, in the nucleon-nucleon frame, from central events. We present preliminary results for source distribution parameters obtained by fitting the two-particle correlation function. The potential for studying kaon correlations in the E802 apparatus is also discussed.
