| Description: |
KASCADE-Grande was designed to study the energy spectrum and mass composition of cosmic rays in the energy range from 10 PeV up to 1 EeV. The measurements revealed a knee-like structure in the heavy components at energies around 100 PeV, consistent with expectations from rigidity-dependent scenarios. In addition, a spectral hardening was observed in the light component near 120 PeV. With the recent release of updated post-LHC hadronic interaction models - QGSJet-III-01, EPOS.LHC-R, and Sibyll 2.3d - we test their validity using KASCADE-Grande data. In this contribution, we present the reconstructed all-particle energy spectra as well as the energy spectra of individual mass groups derived from shower size observables, using the newly released hadronic interaction models. |
