Lepton number
Also known as: lepton charge
- 1Lepton number is a conserved quantum number.
- 2It represents the difference between the count of leptons and antileptons.
- 3It is an additive quantum number preserved in interactions.
- 4The calculation is defined as the number of leptons minus the number of antileptons.
In particle physics, lepton number is a conserved quantum number representing the difference between the number of leptons and the number of antileptons in an elementary particle reaction.

fundamental conservation law investigated in his work
Pontecorvo's studies on neutrino interactions were critical in understanding the conservation of lepton numbers and the differences between neutrino flavors.
In the field of particle physics, lepton number is a conserved quantum number used to track the balance between leptons and antileptons during interactions. It serves as a fundamental accounting tool, ensuring that the total sum of these particles remains constant in any given reaction.
As an additive quantum number, the lepton number is calculated by subtracting the number of antileptons from the number of leptons. This conservation law is essential for understanding the behavior of elementary particles and the constraints governing their transformations in high-energy environments.
