Particle Physics: Conservation & Strange Particles Flashcards
1
Q
Which quantum numbers are always conserved
A
Charge, baryon number, and lepton number
2
Q
When is the weak force responsible for an interaction
A
When strangeness is not conserved and when quark flavour changes
3
Q
How are strange particles created
A
Through the strong interaction, in pairs of strange and antistrange
4
Q
What do kaons decay into, and by what interaction
A
Pions or pions and protons, by the weak interaction
5
Q
Why are strange particles called strange?
A
They have a slightly longer lifespan than was expected
