Comparison of Hadronic Interaction Models at Auger Energies
The engineering array of the southern Pierre Auger Observatory (PAO) [3] in Argentina has recently started to take data. The interpretation of the measurements requires reliable numerical simulations of extensive air showers (EAS) in the extremely-high energy (EHE) range > 10 eV. A large uncertainty in such simulations arises from the models which describe the hadronic interactions. As one has ...
متن کاملLow-Energy Hadronic Interaction Models
Different interaction models treating hadronic collisions below Elab<100 GeV in air shower simulations are compared within the frame of the CORSIKA program. Their behaviour is studied in isolated collisions of protons or pions with light-mass targets in comparison with experimental data. It is discussed how model properties influence air-shower parameters like the longitudinal profile or the la...

Studies of the influence of different hadronic models on extensive air showers at ultra-high energies are presented. The hadronic models considered are those implemented in the well-known QGSJET and SIBYLL event generators. The different approaches used in both codes to model the underlying physics is analyzed using computer simulations performed with the program AIRES. The most relevant observ...

متن کاملHadronic Interactions at Cosmic Ray Energies
General physics of very high energy hadronic interactions is discussed. Special attention is payed to the contribution of semihard processes to the interaction dynamics and to the role of parton shadowing and parton density saturation. In particular, the implementation of non-linear interaction effects in the QGSJET-II model is discussed in detail. The predictions of the model are compared to s...
