So the kaon particle (K) and the sigma particle (Σ) are created very quickly through the strong interaction and decay slowly through the weak interaction.
How is this so? Is this not some kind of discrepancy? What is the explanation for this?
An internet search has lead me to determine that it could be something to do with CP violation. Could it also be to do with the fact that they tend to decay into pions and protons?
I don't want a fully complex mathematical explanation, just a short qualitative one would be great. It's from a past exam paper, and is just a short 2 mark question.
