Ti 中的解决方案钾Z,使用tikzmark
库。
\documentclass[tikz,border=3.141592mm]{standalone}
\usetikzlibrary{tikzmark}
\begin{document}
\begin{tikzpicture}[remember picture,every node/.style={outer sep=2pt},->]
\node {$\Xi^{*-} \rightarrow \tikzmarknode{L1-1}{K}^- + \tikzmarknode{L1-2}\Sigma^0$};
\draw (L1-1) |-++ (.5,-1.5) node[right] {$\tikzmarknode{L4-1}{\pi}^- + \tikzmarknode{L4-2}{\pi}^0$};
\draw (L1-2) |-++ (.2,-.5) node[right] {$\tikzmarknode{L2-1}{\Lambda}^0 + \gamma$};
\draw (L2-1) |-++ (.2,-.5) node[right] {$p+\mathrm{e}^-+\bar{\nu}_{\mathrm{e}}$};
\draw (L4-1) |-++ (.2,-1) node[right] {$\tikzmarknode{L6-1}{\mu}+ \bar{\nu}_\mu$};
\draw (L4-2) |-++ (.2,-.5) node[right] {$\gamma + \gamma$};
\draw (L6-1) |-++ (.2,-.5) node[right] {$\mathrm{e}^- + \bar{\nu}_{\mathrm{e}} + \nu_\mu$};
\end{tikzpicture}
\end{document}
