Test of the KASCADE primary energy spectra by the GAMMA experiment EAS data set

 

The KASCADE primary energy spectra don't describe the GAMMA experiment EAS data set.
Below the detected EAS size spectra and EAS muon truncated spectra are presented (2005)
for SIBYLL and QGSJET interaction models.
The black lines are our predictions according to primary spectra from 0704.3200 [astro-ph] (2007).
The red lines are the corresponding predictions according to the KASCADE primary spectra.

 

 

 

CONCLUSION: The KASCADE primary spectra disagree with GAMMA data set
(presented in 29th ICRC, Pune, India 2005)
We explain the observed disagreement by the very flat
(energy spectral index is about -1.9) KASCADE's Iron energy spectrum
due to pseudo solutions 0706.4087 [astro-ph] (2007).
