![费曼图:重叠的动量和箭头](https://linux22.com/image/400581/%E8%B4%B9%E6%9B%BC%E5%9B%BE%EF%BC%9A%E9%87%8D%E5%8F%A0%E7%9A%84%E5%8A%A8%E9%87%8F%E5%92%8C%E7%AE%AD%E5%A4%B4.png)
我有以下一段代码:
\documentclass[11pt]{article}
\usepackage{tikZ-feynman}
\use[ackage{amsmath}
\begin{document}
\feynmandiagram
[horizontal=d to f1] {
% Draw the top and bottom lines
i1 [particle=\(\nu\)] -- [draw=none] a ,
i2 [particle=\(\mu\)] -- [draw=none] c-- [fermion, momentum'=\(q\mathord-p_2\)] d,
d -- [fermion, momentum'=\(q\mathord+p_1\)] a,
d --[scalar, momentum'=\({p_1\mathord+p_2}\)] f1,
i2 -- [gluon, momentum'=\(k_2\)] a,
i1 -- [gluon, momentum'=\(k_1\)] c,
i1 -- [draw=none] i2,
% Draw the two internal fermion lines
{ [ same layer
] a -- [fermion, momentum'=\(l\)] c },
{ %[ same layer] b -- [anti fermion,edge label=\(\nu_{\mu}\)] d
}
};
\end{document}
但就我而言,我得到了这个:
形状显然不理想。除此之外,我想在传播子的另一侧显示动量 $l$,并解开 $k_1$ 和 $k_2$ 动量的混乱。
