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).]

Particles called B, mesons seemed to be disintegrating into a muon (a cousin of the electron) and an anti-muon more frequently than expected.
This pair can include an electron and its positively charged partner, the positron, or a heavier cousin to an electron, the muon, and its positively charged partner, the anti-muon.
The results demonstrated a 1 per cent difference in the production of pairs of muon (matter) particles and pairs of anti-muons (anti-matter particles) in these high-energy collisions.
