Hadronic 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...
متن کاملHadronic interactions, precocious unification, and cosmic ray showers at Auger energies
At Auger energies only model predictions enable us to extract primary cosmic ray features. The simulation of the shower evolution depends sensitively on the first few interactions, necessarily related to the quality of our understanding of high energy hadronic collisions. Distortions of the standard “soft semi-hard” scenario include novel large compact dimensions and a string or quantum gravity...
متن کاملComparison 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 کاملEnergies of Cosmic-Ray Particles
Cloud chamber photographs of cosmic-ray tracks in a magnetic field up to 17,000 gauss are shown. On the assumption that the particles producing the tracks are travelling downward through the chamber rather than upward, particles of positive charge appear as well as electrons. From the specific ionization along the track it is concluded that the positives are protons, and are not nuclei of charg...
متن کاملSearches for cosmic ray anisotropies at ultra - high energies
We report the different analyses of the arrival directions of ultra-high energy cosmic rays detected at the Pierre Auger Observatory. In the range of energy considered there, two kinds of anisotropies are expected to be observed : point sources at the highest energies and large-scale pattern at lower energies. We report the update of the correlation with Active Galactic Nuclei. Then, from the a...
