ACORDE (ALICE cosmic ray detector) is one of the ALICE
detectors, presently in construction. It will consist of an array of
plastic scintillator counters placed on the three upper faces of the
magnet. This array will act as the cosmic ray trigger for ALICE
calibration, as well as multiple muon trigger to study high energy
cosmic rays. ACORDE, together with other ALICE subdetectors,
will prov

Using data of the L3+Cosmics experiment, a preliminary measurement
of the muon multiplicity distribution is presented.
These are compared to Monte Carlo simulation results obtained with
the CORSIKA/QGSJET code. Below the "knee" of the primary spectrum
20% more muons are observed than expected.
Taking into account the uncertainty of the present primary
spectrum measurements, no abnormal phen

MINOS is the first large magnetic detector deep underground and is the first to
measure the muon charge ratio with high statistics in the region near 1 TeV.
An approximate formula for the muon charge ratio can be expressed in terms of
epsilon_pi = 115 Gev,
epsilon_K = 850 GeV and E_mu times cosine theta-zenith. The implications for
K production in the atmosphere will be discussed.

The 980 ton MINOS Near Detector is located at the end of the NuMI beam facility at
Fermilab in a 100 m deep underground cavern. It was designed to study neutrino
oscillations with the Fermilab NuMI beam in conjunction with the MINOS Far Detector.
The magnetized Near Detector has been recording charge-separated atmospheric
cosmic-ray muons since January 2005. A preliminary measurement of the Mu

The complete 5.4 kton MINOS far detector has been taking charge-separated cosmic ray
muon data since the beginning of August, 2003 at a depth of 2070 meters
water-equivalent in the Soudan mine, Minnesota. The data with both normal and
reversed magnetic field running configurations were combined to minimize residual
systematic errors in the charge ratio. Using the map of the Soudan rock overb

The 5.4 kT MINOS Far Detector (Fardet) has accumulated 45 million
cosmic-ray induced
muon tracks at a depth of 2100 mwe since it began operation in 2003.
An analysis of the muon intensity over the time of detector running
has revealed periodic fluctuations, which are correlated with
temperature fluctuations in the upper atmosphere. This agrees with the
theoretical
expectation for muon

The Pyramid of the Sun, at Teotihuacan, Mexico, is being searched for possible
hidden chambers, using a muon tracking technique inspired in the experiment
carried out by Luis Alvarez over 30 years ago at the Chephren Pyramid, in Giza.
A fortunate similarity between this monument and the Pyramid of the Sun is a
tunnel, running 8 m below the base and ending close to the symmetry axis,
whic
