Kaon HBT radii from perfect fluid dynamics using the Buda-Lund model

Abstract

In this paper we summarize the ellipsoidally symmetric Buda-Lund model's results on HBT radii. We calculate the Bose-Einstein correlation function from the model and derive formulas for the transverse momentum dependence of the correlation radii in the Bertsch-Pratt system of out, side and longitudinal directions. We show a comparison to $\sqrt{s_{\mathrm{NN}}}=200GeV$ RHIC PHENIX two-pion correlation data and make prediction on the same observable for different particles.
