Strangeness Dynamics in Relativistic Nucleus-nucleus Collisions *
We investigate hadron production as well as transverse hadron spectra in nucleus-nucleus collisions from 2 A·GeV to 21.3 A·TeV within two independent transport approaches (UrQMD and HSD) that are based on quark, diquark, string and hadronic degrees of freedom. The comparison to experimental data demonstrates that both approaches agree quite well with each other and with the experimental data on...
متن کاملStrangeness production in proton - proton and proton - nucleus collisions ∗
In these lectures we discuss the investigation of the strange meson production in protonproton (pp) and in proton-nucleus (pA) reactions within an effective Lagrangian model. The kaon production proceeds mainly via the excitations of N(1650), N(1710), and N(1720) resonant intermediate nucleonic states, in the collision of two initial state nucleons. Therefore, the strangeness production is expe...
متن کاملStrangeness enhancement in the String Fusion Model Code
String Fusion Model Code results for Pb–Pb central collisions at SPS energies including the string fusion interaction mechanism are compared to the last experimental data. Predictions for RHIC energies are also presented. On the other hand, the evolution of the strangeness enhancement ratio Es = <Λ>+4 3<π−> with the energy and with the atomic number of participant nuclei is discussed and ...
متن کاملFluctuations and Correlations in hadron-hadron and nucleus-nucleus collisions and String Percolation
Forward-Backward correlations in pp(pp̄) and Nucleus-Nucleus collisions are discussed in the framework of the string percolation model. The point we want to stress is that such correlations, at low energy, increase with energy and the number of participants, at high energies they are extected to decrease with energy and the number of participating nucleons. At RHIC and LHC these predictions can ...
متن کاملMomentum Loss in Proton-Nucleus and Nucleus-Nucleus Collisions
An optical model description, based on multiple scattering theory, of longitudinal momentum loss in proton-nucleus and nucleus-nucleus collisions is presented. The crucial role of the imaginary component of the nucleon-nucleon transition matrix in accounting for longitudinal momentum transfer is demonstrated. Results obtained with this model are compared with Intranuclear Cascade (INC) calculat...
