One of the mysteries of the English language finally explained.
A quantum number assigned to subatomic particles that is ±1 for leptons and 0 for other particles and is conserved in all known interactions.
- ‘When you add the appropriate baryon and lepton numbers and know the beginning charge of both particles, all three of these numbers must be equal before and after the reaction.’
- ‘The observation of the following two decay processes leads to the conclusion that there is a separate lepton number for muons which must also be conserved.’
- ‘You are right that you could suppress such processes by requiring the separate generation lepton numbers to be conserved.’
- ‘It is also possible to compute the average baryon and lepton numbers at finite temperatures and in the relativistic domain.’
- ‘In any reaction between particles, anti or normal, the baryon and lepton numbers must be conserved.’
