Pion Source in Au+Au Collisions at (SNN)=130 GeV
P. Z. Bi
Abstract
The modified model emission function S(x,p), with a uniform radial expansion mode and mass reduction, is used to study the single particle spectra and two particle correlation of pions. The calculated HBT radii and one particle spectra are compared with the data from (SNN)=130 GeV Au+Au collisions at the Relativistic Heavy Ion Collider (RHIC). We see the main features of the data are reproduced, Ro/Rs decreases with increasing Kt and we have a kinetic freeze out temperature T=150 MeV.
