“…In this work, a nonstochastic Pauli blocking was implemented propitiating a time-dependent analysis of multiple particlehole excitations during the cascade process. The method is completely new and provides a more rigorous formalism to address short-range correlations in nuclear matter in comparison with the statistical approaches employed in some refined transport calculations [10], as well as in other cascade models, like the sophisticated Liège INC model [50]. Similarly with the scenario found in low-energy nuclear reactions, forwardangle meson photoproduction processes are also strongly sensitive to the Pauli blocking mechanism due to the typical small-momentum-transfer regime.…”

The mechanism of incoherent π 0 and η photoproduction from complex nuclei is investigated from 4 to 12 GeV with an extended version of the multicollisional Monte Carlo (MCMC) intranuclear cascade model. The calculations take into account the elementary photoproduction amplitudes via a Regge model and the nuclear effects of photon shadowing, Pauli blocking, and meson-nucleus final-state interactions. The results for π 0 photoproduction reproduced for the first time the magnitude and energy dependence of the measured rations σ γ A /σ γ N for several nuclei (Be, C, Al, Cu, Ag, and Pb) from a Cornell experiment. The results for η photoproduction fitted the inelastic background in Cornell's yields remarkably well, which is clearly not isotropic as previously considered in Cornell's analysis. With this constraint for the background, the η → γ γ decay width was extracted using the Primakoff method, combining Be and Cu data [ η→γ γ = 0.476 (62)

“…Long before intermediate energy collisions which are best described by multifragmenation mechanisms, the concept of temperature was being used routinely to describe heavy ion collisions at Bevalac (see for example [16]). In cascade [55] or transport calculations [56] one can follow in microscopic models how the original ordered motion of the beam gets dispersed into a Maxwell-Boltzmann distribution through two-body collisions. In the Purdue experiment of proton on Xe [18], the high energy tails of the kinetic energy spectra provide evidence that the fragments originate from a common remnant system somewhat lighter than the target which disassembles simultaneously into a multibody final system.…”

The equation of state of nuclear matter suggests that at suitable beam energies the disassembling hot system formed in heavy ion collisions will pass through a liquid-gas coexistence region. Searching for the signatures of the phase transition has been a very important focal point of experimental endeavours in heavy-ion collisions, in the last fifteen years. Simultaneously theoretical models have been developed to provide information about the equation of state and reaction mechanisms consistent with the experimental observables.

Using a hadron and string cascade model, JPCIAE, the energy and centrality dependences of charged particle pseudorapidity density in relativistic nuclear collisions were studied. Within the framework of this model, both the relativistic p +p experimental data and the PHOBOS and PHENIX Au + Au data at √ s nn =130 GeV could be reproduced fairly well without retuning the model parameters. The predictions for full RHIC energy Au + Au collisions and for P b + P b collisions at the ALICE energy were given. Participant nucleon distributions were calculated based on different methods. It was found that the number of participant nucleons, < N part >, is not a well defined variable both experimentally and theoretically. Therefore, it is inappropriate to use charged particle pseudorapidity density per participant pair as a function of < N part > for distinguishing various theoretical models.
