Model answer
What a good answer should say
- They violate conservation laws.
Explanation
Why this works
The cause is the violation of conservation laws, which are fundamental principles in physics. The mechanism linking this cause to the effect is that these laws, such as conservation of charge, baryon number, and lepton number, must be satisfied in any interaction.
The effect is that if these laws are violated, the proposed interaction cannot occur, leading to the consequence that such interactions are deemed impossible within the framework of particle physics.
