IceCube is a cubic-kilometer Cherenkov detector in the deep ice at the
geographic South Pole. The dominant event yield is produced by penetrating
atmospheric muons with energies above several 100 GeV. Due to its large
detector volume, IceCube provides unique opportunities to study atmospheric
muons with large statistics in detail. Measurements of the energy spectrum and
the lateral separation distribution of muons offer insights into hadronic
interactions during the air shower development and can be used to test hadronic
models.
We will present an overview of various measurements of atmospheric muons in
IceCube, including the energy spectrum of muons between 10 TeV and 1 PeV. This
is used to derive an estimate of the prompt contribution of muons, originating
from the decay of heavy (mainly charmed) hadrons and unflavored mesons. We will
also present measurements of the lateral separation distributions of TeV muons
between 150 m and 450 m for several initial cosmic ray energies between 1 PeV
and 16 PeV. Finally, the angular distribution of atmospheric muons in IceCube
will be discussed.
