Book Description
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.

Book Description
Significant positive correlations are seen for all charge combinations of pion pairs with small rapidity separation. Joint rapidity-azimuthal correlations show that this positive correlation occurs when like (unlike) pions are produced with small (large) separation in azimuth.

Book Description
This conference brought together the people working on 4π detectors to discuss what had been achieved, whether the results agreed, and to think about possible collaborations to measure the excitation function of several observables. It discussed the similarities and differences in the results obtained at low (100 MeV-1 GeV) and high (10 GeV-200 GeV) energies and outlined what the different fields could learn from each other, especially concerning correlations and particle production. It surveyed the success and also the insufficiency of the present theoretical approaches and discussed the direction in which they have to improve. Finally it gave an account of new developments in data analysis (wavelets, neural networks etc.).
