High Energy Physics in the Atmosphere: Phenomenology of Cosmic Ray Air Showers
Luis Anchordoqui, Maria Teresa Dova, Analisa Mariazzi +4
The properties of cosmic rays with energies above 10**6 GeV have to be deduced from the spacetime structure and particle content of the air showers which they initiate. In this rev…
A reinterpretation of Volcano Ranch lateral distribution measurements to infer the mass composition of cosmic rays
M. T. Dova, M. E. Mancenido, A. G. Mariazzi +2
In the course of its operation, the Volcano Ranch array collected data on the lateral distribution of showers produced by cosmic rays at energies above {\rm eV}. From the…
Hadronic interactions, precocious unification, and cosmic ray showers at Auger energies
Luis Anchordoqui, Haim Goldberg, Jared MacLeod +4
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,…
On the nature of cosmic rays above the Greisen--Zatsepin--Kuz'min cut off
L. A. Anchordoqui, M. Kirasirova, T. P. McCauley +2
A re-examination of the atmospheric cascade profile of the highest energy cosmic ray is presented. The study includes air-shower simulations considering different cross sections, p…
Fractal Electromagnetic Showers
L. A. Anchordoqui, M. Kirasirova, T. P. McCauley +3
We study the self-similar structure of electromagnetic showers and introduce the notion of the fractal dimension of a shower. Studies underway of showers in various materials and a…
Simulation of Water Cerenkov Detectors Using {\sc geant4}
L. A. Anchordoqui, T. P. McCauley, T. Paul +3
We present a detailed simulation of the performance of water Cerenkov detectors suitable for use in the Pierre Auger Observatory. Using {\sc geant4}, a flexible object-oriented sim…
