“…It is found that the magnitude of the cross section decreases with density and the differential cross section becomes more isotropic in medium. Experiments on proton-nucleus scattering [228][229][230] seem to be consistent with these predictions. The N N → N ∆ cross section in medium has been studied in Refs.…”

The change of hadron properties in dense matter based on various theoretical approaches are reviewed. Incorporating these medium effects in the relativistic transport model, which treats consistently the change of hadron masses and energies in dense matter via the scalar and vector fields, heavy-ion collisions at energies available from SIS/GSI, AGS/BNL, and SPS/CERN are studied. This model is seen to provide satisfactory explanations for the observed enhancement of kaon, antikaon, and antiproton yields as well as soft pions in the transverse direction from the SIS experiments. In the AGS heavy-ion experiments, it can account for the enhanced K + /π + ratio, the difference in the slope parameters of the K + and K − transverse kinetic energy spectra, and the lower apparent temperature of antiprotons than that of protons. This model also provides possible explanations for the observed enhancement of low-mass dileptons, phi mesons, and antilambdas in heavy-ion collisions at SPS energies. Furthermore, the change of hadron properties in hot dense matter leads to new signatures of the quark-gluon plasma to hadronic matter transition in future ultrarelativistic heavy-ion collisions at RHIC/BNL.

“…Even though more accurate quark [20], optical [21,22], and relativistic [23] models have been developed, the Tripathi model was chosen because it is used as default in FLUKA (with specific optimisations [16]), TRiP, and SpaceTRiP, it is part of the HK routine used in PHITS, and it is also implemented in Geant4. Additionally, it has many system-dependent free parameters that can be adjusted individually.…”

Nuclear reaction cross-sections are an essential ingredient to reliable deterministic and stochastic radiation transport codes used for radiation protection in space and heavy-ion therapy applications. A recent study compared the existing literature data compiled within the open-access GSI-ESA-NASA cross-section database to the models implemented in the transport codes most commonly used for radiationprotection in space and heavy-ion therapy applications. The outcome of the comparison was that none of the models fit well the experimental data for all projectile-target systems at all energy ranges. Therefore, the literature data were exploited to optimisethe Tripathi model as reported in this work. This model is used as default in FLUKA, TRiP, and SpaceTRiP, it is part of the Hybrid-Kurotama model used in PHITS, and it is implemented in Geant4. The consequences of using the proposed Tripathi optimisation in the Hybrid-Kurotama model are also analysed.
