muon Definition

muon (myo̵̅o̅än′)

noun

Particle Physics an unstable, negatively charged lepton with a mass of 105.7 MeV, c. 207 times that of an electron, and a mean lifetime of 2.2×10 second: it decays into an electron, a neutrino, and an antineutrino

Etymology: mu + (mes)on

muon Usage Examples

Converse of object

  • charge: Topological quantities are particularly important since MINOS will use event shape to identify electron charged current, muon charged current and neutral current events.
  • produce: To be exact, Soudan records muons produced by incoming cosmic rays hitting the atmosphere.
  • use: Marciano reported on the possible muon physics using the muons from a Neutrino Factory.
  • detect: Time travelers Ingrid's experiment will compare the number of muons detected at the top of Cairn Gorm with the number at sea-level.
  • call: For example, there is a particle called the muon which is a heavier cousin of the electron.

Adjective modifier

  • cosmic: The spark chamber shows clearly the tracks of charged particles - in this case, mainly cosmic ray muons from outer space.
  • low: The use of low energy muons is a rapidly developing field with great potential for the study of magnetism near surfaces.
  • positive: A positive muon can, during it's short lifetime, trap an electron to form muonium.
  • only: Muon Detectors: Only muons and neutrinos get this far.

Modifies a noun

  • neutrino: Currenly has the best limit on electron neutrino to muon neutrino oscillations.
  • spin: These are complemented by muon spin relaxation experiments at the ISIS facility, at the Rutherford-Appleton Laboratory in Oxfordshire.
  • beam: Bob also maintains strong collaborations with the international muon beam user community.
  • chamber: The signals the particle produces in the muon chambers are shown as the yellow crosses and the red arrow.
  • experiment: These are complemented by muon spin relaxation experiments at the ISIS facility, at the Rutherford-Appleton Laboratory in Oxfordshire.
  • source: Research within SUPA also makes use of major international facilities, in the UK and overseas, such as neutron and muon sources.

Noun used with modifier

  • energy: The use of low energy muons is a rapidly developing field with great potential for the study of magnetism near surfaces.
  • ray: The spark chamber shows clearly the tracks of charged particles - in this case, mainly cosmic ray muons from outer space.
  • electron: Leptons A family of particles consisting of the electron,the muon and the tau, along with their neutrinos.

Possessives

moment: However, further work may be needed to check and refine the very difficult theoretical calculations on the muon's magnetic moment.

Preposition: in

event: We will create a histogram of the pt of the first muon in each event.
