The L3+C is a unique tool in detecting cosmic muons and measuring
their momenta in the range of 15-3000 GeV/c. About 1.2 x 1010
cosmic muon events have been collected during its running period in
1999-2000. With these high quality data many results on cosmic
rays and gamma rays have been obtained, for example, the measurement
of the atmospheric muon spectrum and the muon...

A measurement is presented of the ratio of positive to negative muon fluxes from
cosmic-ray interactions in the atmosphere, using data collected by the CMS detector
at ground level and in the underground experimental cavern. Muons were detected in
the momentum range from 3 GeV/c to 1 TeV/c. For muon momenta below 100 GeV/c
the flux ratio is measured to be a constant 1.2766 ± 0.0032 (stat)...

When high energy cosmic rays interact in the stratosphere, mesons are produced in the primary hadronic interactions. The MINOS experiment detects cosmic ray produced muons using two magnetized detectors at underground depths of 220 and 2080 mwe. The muon charge ratio and the variation of muon intensity with atmospheric temperature are used to obtain information on meson production by the...

Invited
In the first part of the talk the interesting new results of L3, MINOS and CMS collaborations are briefly discussed from theoretical point of view: an observational evidence of the rise in the muon charge ratio (L3 and MINOS data) at muon energies around 1 TeV and detailed studies of electromagnetic interactions of high energy muons (in a momentum range up to 1 TeV/c) in the medium of CMS...
