The LUCIAE model predictions on the light vector meson production in proton-proton, proton-nucleus and nucleus-nucleus collisions at 158 A GeV
نویسندگان
چکیده
The LUCIAE model predictions are compared with experimental data on light vector meson (ρ, ω, φ) production in pp, p+Pb and Pb+Pb collisions at 158 A GeV. The model reproduces the general trends of the data, but fails in describing the yield of high-pT vector mesons in the central Pb+Pb collisions. Predictions for In+In and p+A (A varying from Be to U) collisions at 158 A GeV are also presented.

Dilepton production in proton-and nucleus-induced reactions is studied in relativistic transport model using initial conditions determined by the string dynamics from RQMD. It is found that both the CERES and HELIOS-3 data for dilepton spectra in proton-nucleus reactions can be well described by the 'conventional' mechanism of Dalitz decay and direct vector meson decay. However, to provide a qu...

The BUU transport model is applied to study strangeness and pion production in nucleus-nucleus collisions. Starting from proton induced reactions, we further investigate Si+Au, Au+Au and Pb+Pb collisions in the energy range between 2 and 40 A·GeV and compare with data and with other transport calculations. The q ¯ q annihilation, or resonance, channel simulated by the string model in meson-nucl...
متن کاملEnergy dependence of J/ψ absorption in proton-nucleus collisions
Charmonium states are expected to be considerably suppressed in the case of quark-gluon plasma formation in high-energy heavy-ion collisions. However, a robust identification of suppression patterns as signatures of a deconfined QCD medium requires a detailed understanding of the “normal nuclear absorption” already present in proton-nucleus collisions, where the charmonium production cross sect...

for the WA97 collaboration) The WA97 experiment studies the production of strange and multistrange particles in Pb{Pb and p{Pb collisions at 158 GeV/c per nucleon. Recent results on and production ratios and transverse mass distributions are reported and compared with those obtained by WA85 and WA94 experiments. A signiicant enhancement of the // ratio has been observed when going from nucleon-...
