Definition

1. Noun:
   • The antiparticle of a lepton: An antilepton is an elementary particle that has the same mass as its corresponding lepton but opposite electric charge and other quantum properties, such as lepton number.

Usage Examples

• Noun:
  • The positron is the antilepton of the electron.
  • In particle collisions, a lepton and an antilepton can annihilate each other.

Advanced Usage

• In particle physics: The term is used to categorize antiparticles within the lepton family, which includes particles like electrons, muons, and taus.
  • The discovery of the muon antineutrino confirmed it as the antilepton of the muon neutrino.

Variants and Related Words

• Lepton (n): The corresponding ordinary matter particle (e.g., electron, muon, tau, and their associated neutrinos).
• Antiparticle (n): The general term for a particle with opposite quantum numbers to its corresponding particle.
• Positron (n): A specific example of an antilepton; the antiparticle of the electron.

Synonyms

• Antiparticle of a lepton: This is the precise synonym, as is a specific technical term.

Related Phrases

• Lepton-antilepton pair: A particle and its corresponding antiparticle produced together.
  • The experiment observed the creation of a lepton-antilepton pair from energy.
• Lepton number conservation: A fundamental rule in physics; the total lepton number (leptons minus antileptons) is conserved in interactions.
  • The reaction is forbidden because it would violate lepton number conservation.
