Universal Pion Freeze-out Phase-Space Density

چکیده
(2) This equation comprises information from essentially two different classes of experimental results: the single particle momentum spectra (dn/dy, Teff), and the two pion Bose-Einstein correlations (Rs, Ro, Rl, Rol, λdir). We have calculated 〈f〉(pT , y) for the S-S, S-Cu, S-Ag, S-Au, S-Pb and Pb-Pb data from the experiments NA35 [2], NA49 [3], NA44 [4], and for the π-p data from the NA22 experiment [5] at CERN-SPS. From the results for 〈f〉 as a function of pT , presented in Fig. 1, one may conclude:

متن کاملDynamics and Sizes of the Fireball at Freeze-out∗
Analyzing the m⊥-spectrum and two-particle correlations of negative hadrons from 158 AGeV/c Pb+Pb collisions at slightly forward rapidities we find a (thermal) freeze-out temperature of about 100 MeV and transverse flow with v̄⊥ ≈ 0.55c. The M⊥-dependence of the correlation radii prefers a box-like transverse density profile over a Gaussian. From an analysis of the pion phase-space density we fi...

The method that allows to analyse an overpopulation of phase-space in heavy ion collisions in model independent way is proposed within hydrodynamic approach. It makes possible to extract a chemical potential of thermal pions at freeze out irrespective of a form of freeze-out (isothermal) hypersurface in Minkowski space and transverse flows on it. The contributions of resonance (with masses up t...
متن کاملUnderstanding of the freeze-out in ultra-relativistic heavy-ion collisions
Hadronic single-particle spectra and correlations carry information about the freeze-out state of the fireball which results from the collective expansion of the strongly interacting matter. Often, the freeze-out state is being modelled in framework of the Cooper-Frye [7] mechanism where all particles − regardless of their identity and/or momentum − are emitted from a single sharp three-dimensi...
