“…Inelastic scatterings of the φ meson include baryonbaryon channels, (N N * )(N N * ) → φNN, and mesonbaryon channels, (πρ)(N N * ) ↔ φ(N N * ), where the cross sections for the forward-going reactions are taken from the one-boson-exchange model [90]. The meson-baryon channels also include K( ) ↔ φN with the cross section taken from a kaon-exchange model [91].…”

We describe in detail how the different components of a multiphase transport (AMPT) model that uses the heavy ion jet interaction generator (HIJING) for generating the initial conditions, Zhang's parton cascade (ZPC) for modeling partonic scatterings, the Lund string fragmentation model or a quark coalescence model for hadronization, and a relativistic transport (ART) model for treating hadronic scatterings are improved and combined to give a coherent description of the dynamics of relativistic heavy ion collisions. We also explain the way parameters in the model are determined and discuss the sensitivity of predicted results to physical input in the model. Comparisons of these results to experimental data, mainly from heavy ion collisions at the BNL Relativistic Heavy Ion Collider, are then made in order to extract information on the properties of the hot dense matter formed in these collisions.

Within a multiphase transport model we study phi meson production in relativistic heavy ion collisions from both superposition of initial multiple proton-proton interactions and the secondary collisions in the produced hadronic matter. The yield of phi mesons is then reconstructed from their decaying product of either the kaon-antikaon pairs or the dimuon pairs. Since the kaon-antikaon pairs at midrapidity with low transverse momenta are predominantly rescattered or absorbed in the hadronic medium, they can not be used to reconstruct the phi meson and lead thus to a smaller reconstructed phi meson yield than that reconstructed from the dimuon channel. With in-medium mass modifications of kaons and φ mesons, the φ yield from dimuons is further enhanced compared to that from the kaon-antikaon pairs. The model result is compared with the experimental data at the CERN/SPS and RHIC energies and its implications to quark-gluon plasma formation are discussed.

“…Extrapolations to the full phase space point to a surprisingly large production cross section. The results of the analysis [7] for the reaction Ni + Ni [5] let one recognise that the calculations based on a transport model underestimate the data by more than a factor of ten. (Notice that refined re-analyses [6,8] of this reaction has shifted the previously reported φ yield [5] to a larger value.)…”
