What is a consequence of a particle interaction violating conservation of lepton number?.
- A.The interaction is allowed.
- B.The interaction cannot occur.
- C.The particles will decay.
- D.The interaction will produce more particles.
Model answer
What a good answer should say
- The interaction cannot occur.
Explanation
Why this works
The cause is the violation of lepton number conservation. The mechanism is that lepton number must remain constant in particle interactions.
The effect is that if lepton number is not conserved, the proposed interaction cannot occur, resulting in the consequence that such interactions are not physically realizable.
