11.7 Exercise 8

Each of the following reactions is missing a single particle. Identify the missing particle for each reaction.

$\begin{matrix}(\text{a}) \text{p} + \overset{−}{\text{p}} \rightarrow \text{n} + ? \\ (\text{b}) \text{p} + \text{p} \rightarrow \text{p} + \Lambda^{0} + ? \\ (\text{c}) \pi^{–} + \text{p} \rightarrow \Sigma^{−} + ? \\ (\text{d}) \text{K}^{−} + \text{n} \rightarrow \Lambda^{0} + ? \\ (\text{e}) \tau^{+} \rightarrow \text{e}^{+} + \nu_{\text{e}} + ? \\ (\text{f}) \left(\overset{−}{\nu}\right)_{\text{e}} + \text{p} \rightarrow \text{n} + ?\end{matrix}$
