Question

Decays of mesons and baryons can be categorized as weak, strong and electromagnetic decays depending upon the interactions involved in the processes. Which of the following option is/are true?

• A. $\pi^0 \rightarrow \gamma \gamma$ is a weak decay.
• B. $\Lambda^0 \rightarrow \pi^0 + p$ is an electromagnetic decay
• C. $K^0 \rightarrow \pi^+ + \pi^-$ is a weak decay.
• D. $\Delta^{++} \rightarrow p + \pi^+$ is a strong decay

Answer 1

Answer: (C), (D)

$K^0 \rightarrow \pi^+ + \pi^-$ is a weak decay.

Answer 2

The correct Answers are (C) :$K^0 \rightarrow \pi^+ + \pi^-$ is a weak decay. ,(D):$\Delta^{++} \rightarrow p + \pi^+$ is a strong decay
