Abstract:
CORSIKA is a detailed program to simulate the evolution of extensive air
showers initiated by high energy cosmic ray particles. Parameter sets
are available to describe the atmosphere at various climatic zones and
seasons. Details of the particle tracking are explained. The hadronic
interactions at high energies may be simulated by five reaction models
alternatively: The VENUS, QGSJET, and DPMJET models are based on Gribov-
Regge theory, SIBYLL is a minijet model, and the phenomenological HDPM
generator is adjusted to experimental data wherever possible. The influence
of those models on observable quantities of air showers are discussed
with emphasis to the muonic component.
