摘要
最近(2024年),NA61/SHINE合作提出了在实验室动量Plab = 13-150 A GeV/c的40Ar + 45Sc中心碰撞中\({{\pi }^{ \pm }}\), \({{K}^{ \pm }}\),质子和反质子产生的新实验数据,并将这些数据与流行理论模型的预测进行了比较。结果表明,这些模型不能很好地描述整个能量范围的数据。在这项工作中,首次提出了参与非衍射碰撞的核子不能在随后的核子-核子碰撞中衍射离解。这个想法已经在Geant4 FTF模型中实现了。对这些数据进行了很好的描述,包括第一个NICA BM@N关于40Ar核与各种能量为3.2 A GeV的核碰撞中\({{\pi }^{ + }}\)介子产生的数据。
On the Theoretical Interpretation of the Data on Collisions of Argon Nuclei with Various Nuclei at High Energies
Recently (2024), the NA61/SHINE collaboration has presented new experimental data on \({{\pi }^{ \pm }}\), \({{K}^{ \pm }}\), proton, and antiproton productions in central 40Ar + 45Sc collisions at the laboratory momenta Plab = 13–150 A GeV/c and has compared these data with predictions of popular theoretical models. It turned out that the models poorly describe the data in the entire energy range. In this work, it has been suggested for the first time that nucleons participating in non-diffractive collisions cannot diffractively dissociate in subsequent nucleon–nucleon collisions. This idea has been implemented in the Geant4 FTF model. Good description of the data, including the first NICA BM@N data on \({{\pi }^{ + }}\) meson production in the collisions of 40Ar nuclei with various nuclei at an energy of 3.2 A GeV, has been achieved.
