The current experimental limit on the muon electric dipole moment, |dμ| < 1.9 × 10 e·cm set by the E821 experiment at the Brookhaven, is … See more

Muons arriving on the Earth's surface are created indirectly as decay products of collisions of cosmic rays with particles of the Earth's atmosphere.
About 10,000 muons reach every square meter of the earth's surface a minute; these charged … See more

The anomalous magnetic dipole moment is the difference between the experimentally observed value of the magnetic dipole … See more

Since muons are much more deeply penetrating than X-rays or gamma rays, muon imaging can be used with much thicker material or, … See more
