标题： Specific Interactions at Cosmic Ray Energies for Extensive Air Showers Experiments

摘要： 使用相对论下强子-核和核-核碰撞的HIJING模型与VENUS模型，研究了强子-强子、强子-氮以及核-氮碰撞的相互作用，这些相互作用对于由宇宙射线在大气中引发的广延大气簇射的发展具有特殊意义。 详细研究了次级粒子的横向能量、横向动量及其谱，并探讨了它们的能量和质量依赖性。 结果着重分析了HIJING模型中的小喷注贡献以及该能区超叠加模型的有效性。 显示英文摘要

摘要： The HIJING and VENUS models of relativistic hadron-nucleus and nucleus-nucleus collisions are used to study interactions of hadron-hadron, hadron-nitrogen and nucleus-nitrogen collisions, specific for the extensive air shower developments initiated by cosmic rays in the atmosphere. The transverse energy, transverse momenta and spectra of secondary particles as well as their energy and mass dependence have been investigated in detail. Results are presented with particular emphasis on the contributions of minijets in HIJING model and validity of superposition models in this energy range.
