I am trying to draw the following figure in Latex. I have drawn it almost but I am not able to draw those curvy line at the respective vertices as shown in the figure attached. How to draw such curve?

• It seems to me that you already achieved what you want – user156344 May 17 at 14:59
• No. When we run those code in latex, those 5 curvy paths are not coming. It is coming as half circle path. – J.Doe May 17 at 15:13
• Yes. I also get that. So you must have the curvy paths as "two child" as above? – user156344 May 17 at 15:14
• yeah..correct. I want like that – J.Doe May 17 at 15:16
• Are those feynman diagrams? – giordano May 18 at 9:14

This is a little modification of your code, using your own coordinates.

I would just define a pic and place it along the paths.

\documentclass[tikz,border=3.14mm]{standalone}
\usetikzlibrary{decorations.markings}
\begin{document}
\begin{tikzpicture}[pics/actor/.style={code={%
\draw[solid] (0,0) -- (0,1) (-1,1.5) to[out=45,in=180] (0,1)
to[out=0,in=60] ++(0.2,0.2) to[out=60,in=60] ++(-60:0.2)
to[out=-120,in=-135] (1,1.5)
;}},
act/.style={postaction={decorate,decoration={markings,
mark=at position #1 with {\pic[transform shape]{actor};}}}}]

\draw[dashed,act/.list={1/3,2/3}] (-2,-2) coordinate(p1)
arc[start angle=270,end angle=90,radius=2]  coordinate(p2);
\draw (p2) -- ++ (2,-1/3) coordinate (p3);
\draw[dashed,act=0.5] (p3) -- ++ (2,-1/3) coordinate (p4);
\draw (p4) -- ++ (2,-1/3) coordinate (p5);
\draw[dashed] (p5) -- ++ (1,-1) coordinate (m)
-- ++ (-1,-1) coordinate (p6);
\pic[rotate=-90] at (m) {actor};
\draw (p6) -- ++ (-2,-1/3) coordinate (p7);
\draw[dashed,act=0.5] (p7) -- ++ (-2,-1/3) coordinate (p8);
\draw (p8) -- (p1);
\foreach \X in {1,...,8} {\draw[fill=white] (p\X) circle[radius=1.5pt];}
\end{tikzpicture}
\end{document}
