Comparison of simulated longitudinal profiles of hadronic air showers with MASS2 balloon data
نویسندگان
چکیده
The KASKADE and CORSIKA air shower generators are compared to the data collected by MASS2 balloon experiment in 1991. The test of longitudinal profile for proton, helium and muon flux production provide good constraints on these air shower generators. KASKADE and CORSIKA especially with the new simulator UrQMD for low energies are found to fit these data well. This study is limited to a comparison of longitudinal profiles and therefore does not provide constraints on the overall shower development.

A neural network approach to event-by-event cosmic ray primary mass identification
An event-by-event study, based on neural network method, of the mass identification in high energy cosmic rays was carried out with simulated data. Extensive air showers were simulated with the CONEX code, using the hadronic model QGSJET-II-3. The goodness of the method in recognizing the mass of the primary was tested making use of the parameters extracted from the simulated longitudinal profi...
متن کامل30TH 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...
متن کاملA Comparative Study of the Depth of Maximum of Simulated Air Shower Longitudinal Profiles
A comparative study of simulated air shower longitudinal profiles is presented. An appropriate thinning level for the calculations is first determined empirically. High statistics results are then provided, over a wide energy range, (1014.0 to 1020.5 eV), for proton & iron primaries, using four combinations of the MOCCA & CORSIKA program frameworks, and the SIBYLL & QGSjet high energy hadronic ...

The interpretation of extensive air shower (EAS) measurements is strongly dependent on the hadronic interaction models used for simulating reference showers. We study the importance of low-energy hadronic interactions in simulated air showers, generated with the simulation package CORSIKA, for the observed characteristics of extensive air showers. In particular we investigate in detail the ener...

The lateral and longitudinal profiles of hadronic showers detected by a prototype of the ATLAS Iron-Scintillator Tile Hadron Calorimeter have been investigated. This calorimeter uses a unique longitudinal configuration of scintillator tiles. Using a fine-grained pion beam scan at 100 GeV, a detailed picture of transverse shower behavior is obtained. The underlying radial energy densities for fo...
