Abstract
Accelerator experiments located at LEP collider have been used also to detect cosmic ray events. Various results obtained by Cosmo-ALEPH, DELPHI and L3+C collaborations are described). Emphasis is put on comparisons of various measurements with Monte-Carlo simulations based on current models of primary hadron-hadron interactions. Analysis of muon momentum spectrum by Cosmo-ALEPH is presented and the link of these measurements to various tests of hadron-hadron interactions models is explained using L3+C data. Cosmo-ALEPH studies of coincident events between distant scintillator stations is briey described. The analyses of multi-muon bundles are explained in more details for all three experiments Cosmo-ALEPH, DELPHI and L3+C. Other topics like source searches by L3+C, ALEPH and DELPHI, L3+C results on anti-proton/proton flux, solar are study, etc. demonstrate large variety of cosmic ray studies at LEP.
