This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Bose-Einstein correlations of[pi][sup+][pi][sup+] and[pi][sup[minus]][pi][sup[minus]] pairs collected by the BNL-E866 Forward Spectrometer in 11.6 A[center-dot]GeV/c Au+ Au collisions have been measured. The data were analyzed using three-dimensional correlation functions parameterized by the Yano-Koonin-Potgoretskii and Bertsch-Pratt formalism to study transverse momentum dependent source parameters. Rapid decreases of longitudinal source radii and slower decreases in the transverse parameters with increasing transverse momentum were observed, which suggests a strong longitudinal and some transverse expansion. A freeze-out time[tau][sub 0] was derived as 4.5--5 fm/c, under the assumption of the freeze-out temperature T= 130 MeV, and the duration of emission was found to be[delta][tau][approx] 2--4 fm/c.

This book was released on 1994 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NA35 experiment has collected a high statistics set of momentum analyzed negative hadrons near and forward of mid-rapidity for central collisions of 200 GeV/Nucleon 32S projectiles incident on S, Ag and Au targets. Using two pion momentum space correlations in order to study the size of the source of particle production, small dependences upon transverse momentum are found for the transverse source dimensions; however for the heaviest system, R{sub long} decreases by about 40% as transverse momentum is increased over the interval 50

Available in PDF, EPUB and Kindle. Book excerpt: 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 [radical]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.

Available in PDF, EPUB and Kindle. Book excerpt: The first measurement of two-pion Bose-Einstein correlations in central Pb-Pb collisions at √sNN=2.76 TeV at the Large Hadron Collider is presented. We observe a growing trend with energy now not only for the longitudinal and the outward but also for the sideward pion source radius. The pion homogeneity volume and the decoupling time are significantly larger than those measured at RHIC.

Available in PDF, EPUB and Kindle. Book excerpt: Two probes of relativistic heavy ion collisions at 200 GeV/A are discussed. The extent of nuclear stopping via measurement of ''proton'' rapidity distributions is presented as a function of centrality. The amount of stopping seen is consistent with what is expected from proton-nucleus data at similar energies. Also, two- pion Bose-Einstein correlations are presented as a function of rapidity and relative transverse momentum. These results are discussed in terms of a simple hydrodynamical model.
