1
Q

2

A
uud -> udd
3
Q
What four properties are conserved in particle interactions?
A
Charge, baryon number, lepton number strangeness.
4
Q
How is strangeness different?
A
It is only conserved in strong interactions.
5
Q
Why isn’t strangeness conserved in weak interactions?
A
In weak interactions, strangeness can change by -1, 0 or +1.
6
Q
How is lepton number different?
A
Different types of lepton number have to be conserved separately.
7
Q
What is quark confinement
A
It isn’t possible to get a quark by itself.
