“…Historically, a great achievement of KASCADE was the invention of the air-shower simulation tool CORSIKA (COsmic Ray SImulation for KAscade), which meanwhile is used by all major air-shower experiments worldwide [14]. Mainly data of the hadron calorimeter and additional muon counters at the central detector and the muon tunnel were used within KASCADE to iteratively test and improve the various versions of the hadronic interaction models optionally available in CORSIKA (see e.g., [15,16] and references therein). Regarding the analysis of KASCADE and KASCADE-Grande data one has to conclude that all versions of hadronic interaction models of newest generation provide a 'physical' result in terms of energy and composition of primary cosmic rays.…”

The 'KASCADE Cosmic ray Data Centre' is a web portal (https://kcdc.ikp.kit.edu), where the data of the astroparticle physics experiment KASCADE-Grande are made available for the interested public. The KASCADE experiment was a large-area detector for the measurement of high-energy cosmic rays via the detection of extensive air showers. The multi-detector installations KASCADE and its extension KASCADE-Grande stopped the active data acquisition in 2013 after more than 20 years of data taking. In several updates since our first release in 2013 with KCDC we provide the public measured and reconstructed parameters of more than 433 million air showers. In addition, KCDC provides meta data information and documentation to enable a user outside the community of experts to perform their own data analysis. Simulation data from three different high a

High energy physics in the atmosphere: phenomenology of cosmic ray air showers

The properties of cosmic rays with energies above 10 6 GeV have to be deduced from the spacetime structure and particle content of the air showers which they initiate. In this review we summarize the phenomenology of these giant air showers. We describe the hadronic interaction models used to extrapolate results from collider data to ultra high energies, and discuss the prospects for insights into forward physics at the LHC. We also describe the main electromagnetic processes that govern the longitudinal shower evolution, as well as the lateral spread of particles. Armed with these two principal shower ingredients and motivation from the underlying physics, we provide an overview of some of the different methods proposed to distinguish primary species. The properties of neutrino interactions and the potential of forthcoming experiments to isolate deeply penetrating showers from baryonic cascades are also discussed. We finally venture into a terra incognita endowed with TeV-scale gravity and explore anomalous neutrino-induced showers.

“…Hadronic shower observables with sensitivity to interaction features have for instance been discussed in [4,6]. A specific, further observable that is based on the four most energetic hadrons in each event as is λ 4 , is given by the maximum distance, d max 4 , between one of the four considered hadrons to the geometric centre of the other three [26].…”

“…In other studies, data taken by the KAS-CADE scintillator array and hadron calorimeter [2,3] were used to investigate different aspects of hadronic interaction models. The correlation of the hadronic to the muonic and electromagnetic shower components [4,5], as well as features of the particle production in the very forward region of nucleon-air collisions [6] were measured and compared to model predictions.…”

The geometric distribution of high-energy hadrons ≥100 GeV in shower cores measured with the KASCADE calorimeter is analyzed. The data are checked for sensitivity to hadronic interaction features and indications of new physics as discussed in the literature. The angular correlation of the most energetic hadrons and in particular the fraction of events with hadrons being aligned are quantified by means of the commonly used parameter λ4. The analysis shows that the observed λ4 distribution is compatible with that predicted by simulations and is not linked to an angular correlation from hadronic jet production at high energy. Another parameter, d max 4, describing distances between hadrons measured in the detector, is found to be sensitive both to the transverse momenta in secondary hadron production and the primary particle type. Transverse momenta in high-energy hadron interactions differing by a factor two or more from what is assumed in the standard simulations are disfavoured by the measured d distribution.
