A quantum number assigned to subatomic particles that is ±1 for leptons and 0 for other particles and is conserved in all known interactions.
〔物〕轻子数
Example sentencesExamples
You are right that you could suppress such processes by requiring the separate generation lepton numbers to be conserved.
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.
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.
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.
