调平费曼图的基础

Question

我正在使用 绘制费曼图tikz-feynman。当我画的时候

    };
        
    \end{feynman}
\end{tikzpicture}
}
\end{document}

相邻的图形不在同一层级。

具体来说，我希望水平线处于同一水平。如何使它们处于同一水平？

Answer 1

你应该做两件事：

1. 不要将tikzpictures 放在 es 内\scalebox，而是使用scale选项。对于tikz-feynman图表，您需要transform shape另外使用以确保缩放正常工作。您可以取消缩放节点，以确保两个图表中的字体大小相同。我创建了一个可以自动执行此操作的自定义.style。
2. 使用该baseline选项来引用要为两个图设置基线的节点。我为两个图选择了最右边的坐标。

\documentclass{article}
\usepackage[compat=1.1.0]{tikz-feynman}

\tikzset{
    feynman scale/.style={
        transform shape,
        scale={#1},
        every node/.append style={
            scale={1/#1}
        },
    }
}

        \vertex[above right=of a2](a3);
        \vertex[below right=of a2](a4);
        \vertex[below right=of a3] (a5);
        \vertex[right=of a5] (d);
        \diagram* {
