Chapter 44: Q18P (page 1364)

Question: By examining strangeness, determine which of the following decays or reactions proceed via the strong interaction: (a) $K^{0} \to π^{+} + π^{-}$ (b) $Λ^{0} + p \to Σ^{+} + n$ (c) $Λ^{0} \to p + π^{-}$ (d) $K^{-} + p \to Λ^{0} + π^{0}$ .

Short Answer

Expert verified

Strangeness is not conversed.
Strangeness is not conversed.
Strangeness is not conversed.
Strangeness is conversed.

Step by step solution

(a) Strangeness of K0→π++π-.

The strangeness of $K^{0}$ is $+ 1$ and the strangeness of $π^{+}$ is 0 and strangeness of $π^{-}$ is $0$ .

Thus, strangeness is not conversed.

Hence, it does not proceed via strong interaction.

(b) Strangeness of Λ0+p→∑++n.

The strangeness of $Λ^{0}$ is $- 1$ and $p$ is $0$ and the strangeness $\sum^{+}$ of is $1$ and strangeness of $n$ is $0$ .

Thus, strangeness is not conversed.

Hence, it does not proceed via strong interaction.

(c) Strangeness of Λ0→p+π- .

The strangeness of $Λ^{0}$ is $- 1$ and the strangeness of $p$ is $0$ and $π^{-}$ is $0$ .

Thus, strangeness is not conversed.

Hence, it does not proceed via strong interaction.

(d) Strangeness of K-+p→Λ0+π0 ..

The strangeness of $K^{-}$ is $- 1$ and $p$ is $0$ and the strangeness of $Λ^{0}$ is $- 1$ and $π^{0}$ is $0$ .

Thus, strangeness is conversed.

Hence, it proceed via strong interaction.
