我使用 LaTeX 编写了此代码tikz-feynman
,但它无法编译:
\begin{figure}
\centering
\feynmandiagram[horizontal=a to b]{
i1 [particle={\(\Lambda\)}] -- [fermion] a [crossed dot] -- [fermion] i2 [particle={\(n\)}],
i2 -- [fermion] i3 [particle={\(k\)}] ,
i1 -- [draw=none] f1 [particle={\(\Lambda\)}],
i3 -- [draw=none] f3 [particle={\(\Lambda\)}],
a -- [charged scalar, edge label=\(\eta\)] b,
i2 -- [charged scalar, edge label=\(\eta\)] f2,
f1 -- [fermion] b -- [fermion] f2 ,
f2 -- [fermion] f3 [particle={\(n2\)}] ,
};
