Investigation of EAS Muon Pseudorapidity in KASCADE-Grande. — •Janusz Zabierowski2, Paul Doll1, Kai Daumiller1, Pawel Luczak2, and Ralf Obenland1 for the KASCADE-Grande collaboration — 1Institut für Kernphysik, Forschungszentrum Karlsruhe, Postfach 3640, 76021 Karlsruhe — 2Soltan Institute for Nuclear Studies, 90950 Lodz, Poland
The Muon Tracking Detector in KASCADE-Grande experiment allows measurement of muon directions up to 700m from the shower centre. It means, that nearly all muons produced in a shower and surviving to the ground level are subject of investigation. This is not only important for the investigation of the muon production height but also for a study of EAS muon pseudorapidity distributions which in this case are nearly identical to the pseudorapidity distributions of their parent mesons produced in hadronic interactions. Experimental data on lateral distribution of mean muon pseudorapidity and its dependence on the primary energy will be presented and compared to predictions from the Monte Carlo CORSIKA simulations.
