LHC studies relevant to PeV - EeV cosmic ray physics

Abstract

At the CERN LHC collider, where p-p collision energies will be equivalent to 100 PeV cosmic ray interactions, the ambiguity of interaction models needed for the interpretation of V.H.E. cosmic ray data is recognized, and relevant inclusive data at high pseudorapidities from p-p and nucleus-nucles interactions will be obtained. In this context, the parameters and plans of the CMS, CASTOR, and TOTEM detectors will be noted.
