  • The structure functions should not depend on whether the probing charged leptons are muons or electrons.
  • charged leptons
  • lepton flavor
  • quarks and leptons

Examples

  • In thinking about defining the leptons, it is useful to remember that they are not force-carrying particles.

    Academic text (1997)
  • These particles come in two families, the family of leptons and the family of hadrons.

  • And the reason is that lepton number is not really thought to be conserved, right?

  • The search for new leptons has expanded in yet other directions.

    Academic text (1997)
  • Over the course of a century, six leptons have been discovered in the universe of elementary particles.

    Academic text (1997)
  • These are the quarks, these are the leptons, these are the force carriers.

  • Thus, each of the three known neutrinos is associated with a specific charged lepton (summarized in Table 2).

    Academic text (1997)
  • And, and so the quarks are quarks and the leptons are things like electrons and muons.

  • We've learned so much from the study of deep inelastic scattering of longitudinally polarized leptons and hadrons.

    Academic text (1995)
  • In particle physics, a lepton is a type of subatomic particle, such as the electron, that does not engage in strong nuclear interactions.

Etymology

Lepton comes from the Greek word leptos meaning 'small' or 'thin', and scientists borrowed the name for very small particles like electrons and neutrinos, so the word points to their tiny size.
