چکیده

The geometrical structure of high-energy hadrons in shower cores measured with the KASCADE calorimeter is analyzed. The angular correlation, especially the degree of alignment, is quantified by means of the commonly used parameter λ4. The λ4 distribution obtained by KASCADE is comparable to that derived by other experiments. The analysis shows that the observed λ4 distribution is not linked to angular correlations due to jet production at high energies. The dependence on the transverse momentum pt in the simulation of hadronic interactions is marginal. In contrast to λ4, the maximum distance d max 4 between the most-energetic hadrons reveals a sensitivity both on pt and the primary mass.

30TH INTERNATIONAL COSMIC RAY CONFERENCE Test of hadronic interaction models with data from the Pierre Auger Observatory

The Pierre Auger Observatory allows the measurement of both longitudinal profiles and lateral particle distributions of high-energy showers. The former trace the overall shower development, mainly of the electromagnetic component close to the core where the latter reflect the particle densities in the tail of the shower far away from the core and are sensitive to both the muonic and electromagn...

Search for elongated spatial structures in hadronic shower cores with KASCADE

In this analysis the structure of hadronic shower cores is investigated with the KASCADE calorimeter. The energy, position, and direction of incidence for individual hadrons above 50 GeV are measured. In parallel, the spatial structure is studied using the simulation program CORSIKA with the hadronic interaction model QGSJET. First results are presented for the showers with primary energies abo...
