Answer
To examine conservation laws associated with proposed reaction
$$\mathrm{p}+\overline{\mathrm{p}} \rightarrow \Lambda^{0}+\Sigma^{+}+e^{-},$$ we make use of particle properties found in Tables $44-3$ and $44-4 $ with $$q(\mathrm{p})=+1, q(\overline{\mathrm{p}})=-1,$$
$$ q\left(\Lambda^{0}\right)=0, \quad q\left(\Sigma^{+}\right)=+1,$$
$$ \text { and } q\left(e^{-}\right)=-1,$$
we have
$1+(-1)=0+1+(-1) . $
$$\text { Thus, the process conserves charge. } $$
