SUMMARY:Probing hadronic interactions with atmospheric leptons\, NPAC 
 (Nuclear/Particle/Astro/Cosmo) Forum\, Anatoli Fedynitch\, Karlsruhe
DESCRIPTION:Inclusive fluxes of muons and neutrinos in the atmosphere 
 provide a continuous source of information about the spectrum and comp
 osition of cosmic rays interacting with air nuclei. Furthermore\, meas
 urements of the fluxes allow us to learn more about hadronic interacti
 ons in phase space regions not accessible at high-energy colliders. Us
 ing an accurate and flexible solution of the coupled cascade equations
 \, called matrix-method\, it is possible to study numerically the conn
 ection between atmospheric muon observations and measurements made at 
 fixed-target or collider experiments. I will present the status of lep
 ton <br>
\nflux calculations using different interaction models and pr
 imary cosmic ray flux assumptions. Emphasis is put on the role of hadr
 onic interactions by discussing the importance of different phase-spac
 e regions\, particle species and interaction energies for the predicti
 on of atmospheric lepton fluxes.
