Cosmic-ray physics in ALICE at CERN

ALICE is one of the four main experiments at the CERN Large Hadron Collider. Thelocation of the ALICE detector allows us to study the muonic component of cosmicrays, since it is located 52 meters underground with 28 meters of rock above it.The ALICE detector is able to detect atmospheric muons from extensive airshowers, making possible the study of topics related to cosmic-ray physics. Atthis depth, only atmospheric muons with energies greater than 16 GeV can reachthe detection zone. The analysis of the multiplicity distribution of atmosphericmuons reconstructed by the Time Projection Chamber (TPC) of ALICE is presented.The comparison with post LHC hadronic interaction models solves the longstanding issue of the rate of events with an extremely large multiplicity ofmuons.
