Sensitivity of Extensive Air Showers to Features of Hadronic Interactions at Ultra-High Energies
Ralf Ulrich, Ralph Engel, Steffen Müller +3
We study the dependence of extensive air shower development on the first hadronic interactions at ultra-high energies occurring in the startup phase of the air shower cascade. The…

On the measurement of the proton-air cross section using air shower data
Ralf Ulrich, Johannes Blümer, Ralph Engel +2
The analysis of high-energy air shower data allows one to study the proton-air cross section at energies beyond the reach of fixed target and collider experiments. The mean depth o…

Reconstruction of Longitudinal Profiles of Ultra-High Energy Cosmic Ray Showers from Fluorescence and Cherenkov Light Measurements
M. Unger, B. R. Dawson, R. Engel +2
We present a new method for the reconstruction of the longitudinal profile of extensive air showers induced by ultra-high energy cosmic rays. In contrast to the typically considere…
