科西卡：一个模拟大范围空气簇射的蒙特卡罗程序CORSIKA是一个详细模拟由高能宇宙射线粒子引发的大范围空气簇射的程序。质子、轻原子核到铁、光子和许多其他粒子都可以被当作原色。粒子在大气中被追踪，直到它们与空气核发生反应或发生不稳定的二次衰变。高能强子相互作用可以用五种不同的反应模型来描述：VENUS、QGSJET和DPMJET模型是基于Gribov-Regge理论的，而SIBYLL模型是一种微型喷注模型。HDPM是一种现象发生器，并尽可能根据实验数据进行调整。低能强子相互作用可以用更复杂的GHEISHA相互作用程序或相当简单的ISOBAR模型来描述。在粒子衰变中，所有衰变分支都被考虑到1%的水平。对于电磁相互作用，可以使用簇射程序EGS 4或解析NKG公式。存在产生切伦科夫辐射和中微子的选择。
CORSIKA: A Monte Carlo Code to Simulate Extensive Air Showers CORSIKA is a program for detailed simulation of extensive air showers initiated by high energy cosmic ray particles. Protons, light nuclei up to iron, photons, and many other particles may be treated as primaries. The particles are tracked through the atmosphere until they undergo reactions with the air nuclei or in the case of instable secondaries decay. The hadronic interactions at high energies may be described by five reaction models alternatively: The VENUS, QGSJET, and DPMJET models are based on the Gribov-Regge theory, while SIBYLL is a minijet model. HDPM is a phenomenological generator and adjusted to experimental data wherever possible. Hadronic interactions at lower energies are described either by the more sophisticated GHEISHA interaction routines or the rather simple ISOBAR model. In particle decays all decay branches down to the 1% level are taken into account. For electromagnetic interactions the shower program EGS4 or the analytical NKG formulas may be used. Options for the generation of Cherenkov radiation and neutrinos exist.
