mu·on

 (myo͞o′ŏn′)
n.
The negatively charged lepton that belongs to the second generation of elementary fermions and has a mass 207 times that of an electron and a mean lifetime of 2.2 × 10-6 second. Also called mu lepton.

[Earlier mu meson (from the use of the Greek letter mu, the equivalent of the Roman letter m of meson, to distinguish it from other mesons subsequently discovered, the class of particles to which it was formerly thought to belong).]

mu·on′ic adj.

muon

(ˈmjuːɒn)
n
(General Physics) a positive or negative elementary particle with a mass 207 times that of an electron and spin . It was originally called the mu meson but is now classified as a lepton

muonic adj

mu•on

(ˈmyu ɒn)

"The best description of a muon would be a very heavy electron -- but a muon is a couple hundred times more massive than an electron," Melott said.
The collision produced a heavy cousin of the electron called a muon, which left a track of dim, bluish light in the IceCube detector.
Together, Qahtani and Mohamed are using Texas A&M at Qatar's supercomputer, Raad2, to simulate a new detector called the gas electron multiplier (GEM) that will be installed in the muon chamber in CERN's Large Hadron Collider's Compact Muon Solenoid (CMS) project, which detects the muons that are generated from the proton-proton collisions.

But if we consider, for example, Bailey et al's muon experiment [2], we find that there is no contradiction with the experimental observations: a perceived time dilation is observed in the Earth's laboratory frame of reference while the muon, in its frame of reference has no time dilation--note that no measurements were carried out in the muon's frame of reference in the Bailey experiment.
