“…• The higher energies at CERN also generate a stronger longitudinal expansion of the matter, requiring at least cylindrical symmetry for the model, which we will introduce in the next section, to describe the data. The BNL data for the pions [7] are closer to an isotropic momentum distribution and might be described well by a spherically symmetric model as we have presented one already some time ago [8].…”

“…This rephrases the fact that the rapidity distribution of massless particles from an isotropic source is always the same regardless of their momentum dependence (e.g. [7]). Its full width at half height Γ fwhm th ≈ 1.76 is in sharp contrast to the experimental value for the pions of Γ fwhm exp = 3.3 ± 0.1 [5] (see dotted line in Fig.…”

Thermal phenomenology of hadrons from 200AGeV S+S collisions

1993

We develop a complete and consistent description for the hadron spectra from heavy ion collisions in terms of a few collective variables, in particular temperature, longitudinal and transverse flow. To achieve a meaningful comparison with presently available data, we also include the resonance decays into our picture. To disentangle the influences of transverse flow and resonance decays in the m T -spectra, we analyse in detail the shape of the m T -spectra.

“…The pseudorapidity (77 = -In tan 1912) distributions for central collisions of oxygen projectiles at 14.6, 60, and 200 GeV/nucleon were analyzed by us earlier [27]. The inclusive pseudorapidity distributions of shower particles N,, produced in proton, oxygen, and sulfur interactions in nuclear emulsion are shown in Fig.…”

Oxygen and sulfur nuclei with energies of 200 GeV/nucleon have been allowed to interact in nuclear emulsions exposed at CERN. These emulsions have been scanned with a minimum bias so that essentially all the interactions occurring were detected. Nearly 1000 interactions of each projectile have been analyzed. We present results on the multiplicity distributions, the pseudorapidity distributions, and the fragmentation of the projectile and target nuclei. It is shown that the mean number of intranuclear collisions in each interaction, calculated from a superposition model, provides a useful parameter for organizing the data. We conclude that there are no significant deviations even at these energies from models, such as the VENUS model, describing the interactions as being the superposition of individual nucleon-nucleon collisions.

“…In order to compare the results with the observed particle distributions, the shape of the assumed confining volume could play an important role. It has long been known that the particle momentum distributions are somewhat forward-backward peaked, particularly at energies of the SPS [11], even in the case of central collisions. Nevertheless, for the sake of simplicity and concreteness, here we will assume that the confining volume is spherical.…”

Boundary and expansion effects on two-pion correlation functions in relativistic heavy-ion collisions

We examine the effects that a confining boundary together with hydrodynamical expansion play on two-pion distributions in relativistic heavy-ion collisions. We show that the effects arise from the introduction of further correlations due both to collective motion and the system's finite size. As is well known, the former leads to a reduction in the apparent source radius with increasing average pair momentum K. However, for small K, the presence of the boundary leads to a decrease of the apparent source radius with decreasing K. These two competing effects produce a maximum for the effective source radius as a function of K.PACS numbers: 25.75.Gz, 25.75.Ld
