Geant4 FTF模型描述NA61/SHINE协作组关于${\rm ^{40}Ar+{}^{45}Sc}$相互作用的最新数据
Geant4 FTF model description of the latest data by the NA61/SHINE collaboration on ${\rm ^{40}Ar+{}^{45}Sc}$ interactions
摘要：
结果表明，Geant 4 FTF模型（不包括硬部分子-部分子散射和夸克-胶子等离子体（QGP）形成的模拟）较好地描述了$\sqrt{s_{NN}}=$ 5.2，6.1，7.6和8.8 GeV的$π^-$介子分布的NA 61/SHINE数据.在更高的能量，$\sqrt{s_{NN}}=$ 11.9和16.8 GeV，模型低估了数据。这被认为是在更高的能量轻和中间核的碰撞比在碰撞的重核（$\sqrt{s_{NN}}\sim 6$ GeV）的QGP的形成的指示。
英文摘要：
It is shown that the Geant4 FTF model, which does not include the simulation of the hard parton-parton scattering and the formation of the quark-gluon plasma (QGP), describes well the NA61/SHINE data on $π^-$ meson distributions for the interactions at $\sqrt{s_{NN}}=$ 5.2, 6.1, 7.6 and 8.8 GeV. At higher energies, $\sqrt{s_{NN}}=$ 11.9 and 16.8 GeV, the model underestimates the data. This is considered as an indication of the formation of QGP at higher energies in central collisions of light and intermediate nuclei than in collisions of heavy nuclei ($\sqrt{s_{NN}}\sim 6$ GeV).
