12th International Conference on Elastic and Diffractive Scattering (Blois Workshop) - Forward Physics and QCD
J. Bartels, K. Borras, M. Diehl +118
Proceedings of the 12th International Conference on Elastic and Diffractive Scattering (Blois Workshop) - Forward Physics and QCD
Correlation of the highest-energy cosmic rays with the positions of nearby active galactic nuclei
The Pierre Auger Collaboration
Data collected by the Pierre Auger Observatory provide evidence for anisotropy in the arrival directions of the cosmic rays with the highest energies, which are correlated with the…
On the measurement of the proton-air cross section using cosmic ray data
Ralf Ulrich, Johannes Bluemer, Ralph Engel +2
Cosmic ray data may allow the determination of the proton-air cross section at ultra-high energy. For example, the distribution of the first interaction point in air showers reflec…
On the relation between the proton-air cross section and fluctuations of the shower longitudinal profile
R. Ulrich, J. Blümer, R. Engel +2
The current status and prospects of deducing the proton-air cross section from fluorescence telescope measurements of extensive air showers are discussed. As it is not possible to…
Study of the Cosmic Ray Composition above 0.4 EeV using the Longitudinal Profiles of Showers observed at the Pierre Auger Observatory
Michael Unger
The Pierre Auger Observatory has been collecting data in a stable manner since January 2004. We present here a study of the cosmic ray composition using events recorded in hybrid m…
