Cosmic Ray: Theoretical Implications

According to recent measurements the tendency of the chemical composition above the ankle is characterized by increasing fractions of intermediate and heavy nuclei and a dominance of light nuclei around the ankle featured by a minimum of the log(A) profile. Calculations of the chemical composition in the range 3.5x10**18-5x10**19 eV according to new principles are reported and compared with...

Cosmic Ray: Theoretical Implications

Ultra High Energy Cosmic Rays experimental data are now of very good statistical significance even in the region of the expected GZK feature. The identification of their sources requires sophisticate analysis of their propagation in the extra galactic space. When looking at the details of this propagation some unforeseen features emerge. I will discuss some of these "surprises".

Cosmic Ray: Theoretical Implications

With the LHC basically reaching its design beam energy the measurements most relevant for the cosmic ray community are becoming available. First data do not indicate major difficulties within the existing interaction models. An eventual new generation of updated models to describe LHC data at 13TeV will further lower the model discrepancies at ultra-high energies. The cosmic ray community has...
