1.5 Strange Particles and Conservation of Properties Flashcards
1
Q
How are strange particles created?
A
They are created via the strong interaction
2
Q
When are strange particles conserved?
A
In the strong interaction
In the weak interaction they can change by -1, 0 or +1
3
Q
How are strange particles created?
A
In pairs
4
Q
What strangeness value do leptons have?
A
0
5
Q
Do strange particles decay?
A
Yes, through the weak interaction
6
Q
What properties are conserved in all particle interactions?
A
- energy
- momentum
- charge
- baryon number
- lepton number
- strangeness (in the strong interaction only)
7
Q
How are lepton numbers conserved?
A
Electron, muon and tau lepton numbers are conserved separately - as if they are different properties
