Two-particle correlations have been measured for identified \(\pi^-\) from central 158 A GeV Pb+Pb collisions and fitted radii of about 7 fm in all dimensions have been obtained. A multi-dimensional study of the radii as a function of \(k_T\) is presented, including a full correction for the resolution effects of the apparatus. The cross term \(R^2_{out-long}\) of the standard fit in the Longitudinally CoMoving System (LCMS) and the \(v_L\) parameter of the generalised Yano-Koonin fit are… Expand

Two-kaon correlations in central Pb+Pb collisions at 158 a GeV/c.
Two-particle interferometry of positive kaons is studied in Pb+Pb collisions at mean transverse momenta approximately 0.25 and 0.91 GeV/c to find that the source-size parameters are consistent with the m(T) scaling curve observed in pion-correlation measurements in the same collisions. Expand
One-, two-, and three-particle distributions from 158A GeV/c central Pb+Pb collisions
Several hadronic observables have been studied in central 158A GeV Pb+Pb collisions using data measured by the WA98 experiment at CERN: single pi(-) and K- production, as well as two- and three-pionExpand
Pion interferometry in Au+Au collisions at root s(NN)=200 GeV
We present a systematic analysis of two-pion interferometry in Au+Au collisions at {radical}(s{sub NN})=200 GeV using the STAR detector at Relativistic Heavy Ion Collider. We extract theExpand
Hanbury-Brown-Twiss interferometry with quantum transport of the interfering pair
In the late stage of the evolution of a pion system in high-energy heavy-ion collisions when pions undergo multiple scatterings, the quantum transport of the interfering pair of identical pions playsExpand
Correlations in STAR: interferometry and event structure
STAR observes a complex picture of RHIC collisions where correlation effects of different origins–initial state geometry, semi-hard scattering, hadronization, as well as final state interactions suchExpand
Vector manifestation and matter formed in relativistic heavy-ion processes
Abstract Recent developments in our description of RHIC and related heavy-ion phenomena in terms of hidden local symmetry theories are reviewed with a focus on the novel nearly massless states in theExpand
Genuine three-body Bose–Einstein correlations and percolation of strings
Abstract Recent data show a large difference of the genuine three-body Bose–Einstein correlations in S–Pb collisions and in Pb–Pb central collisions being close to zero in the first case and to oneExpand
Levy distributions for one-dimensional analysis of the Bose- Einstein correlations
A general study of relations between the parameters of two centrally-symmetric Levy distributions, often used for one-dimensional investigation of Bose - Einstein correlations, is given for the firstExpand
Correlations and fluctuations in high energy heavy ion collision experiments
An overview of research status of soft physics in high energy heavy-ion collision experiments and recent experimental results are presented. The experimental status on fluctuations and correlationsExpand
Intensity interferometry for a chaotic source with a collective flow and multiple scattering
We study the effects of a collective flow and multiple scattering on two-particle correlation measurements in Hanbury-Brown–Twiss (HBT) intensity interferometry. While the derivation in this paper isExpand
