Air Shower coincidences in the CosmoALEPH experiment — •Mehmet Tahir Kurt — Universitaet Siegen, Emmy-Noether-Campus D-57068 SIEGEN

Coincidences between five scintillator telescopes and the hadron calorimeter of the ALEPH experiment are analysed for the period between 24 April and 13 October 2000. The observed two-fold and three-fold coincidences are compared to the expected muon lateral distributions based on a fast Monte Carlo simulation and analytical expression derived from the propagation of extensive air shower through the atmospehere and the overburden above the muon air shower array.
