Conservation

Question 1

What must be conserved during particle interactions?

Answer 1

Charge (Q)
Lepton Number (L)
Baryon number (B)
Strangeness - (sometimes)

Question 2

What is the lepton number?

Answer 2

All leptons have a lepton number,
Normal particles: +1
Anti-particles: -1

Question 3

What is the baryon number?

Answer 3

All baryons have a baryon number:
Normal baryons: +1
Anti-baryons: -1

Note: Mesons do NOT have a baryon number.

Question 4

How does the conservation of strangeness work?

Answer 4

Strangeness must be conserved within strong inertacions.
Strangeness can be conserved or +- 1 within weak interactions.
