muon muon


  • (n) an elementary particle with a negative charge and a half-life of 2 microsecond; decays to electron and neutrino and antineutrino



  1. Be cause the muon leaves a wake of ionized gas, which conducts electricity, a spark will jump between each pair of plates along the path of the particle.
  2. One clue was the detection of a muon, a close relative of the electron.
  3. Bahcall and Bethe speculate that electron neutrinos change into the muon or tau versions somewhere between the sun and Earth.
