lepton
Definition
- Noun:
- An elementary particle that participates in weak interactions; has a baryon number of 0: In particle physics, a "lepton" is a fundamental particle that does not undergo strong interactions. The most familiar leptons are the electron and the neutrino.
- A former monetary unit of Greece equal to one hundredth of a drachma: In a historical and numismatic context, a "lepton" was a small Greek coin.
Examples of Usage
- Noun (Physics):
- The electron is a stable, negatively charged lepton.
- Neutrinos are elusive leptons with very little mass.
- Noun (Currency):
- The coin was worth only a single lepton.
- In the parable, the widow's mite was worth two lepta.
Advanced Usage
- The term is often used in the plural form "leptons" when discussing particle physics as a category.
- The Standard Model classifies fundamental particles into quarks and leptons.
- In historical texts, the plural "lepta" is used for the currency.
- He donated his last two lepta to the temple.
Variants and Related Words
- Leptonic (adj): Pertaining to leptons.
- Leptonic decays involve only leptons and neutrinos.
- Lepton number (n): A quantum number conserved in particle interactions.
- Electron neutrino production conserves lepton number.
Synonyms
- Elementary particle (for the physics sense): A fundamental constituent of matter.
- Subatomic particle (for the physics sense): A particle smaller than an atom.
Different Meanings
- The two primary meanings are distinct and belong to completely different fields (physics and historical finance). Context is essential to determine which is intended.
