I am trying to draw Feynman diagram with feynarts.sty in MikTek2.9.

However, I get diagram with nothing only label.

This is the same problem as Feynman diagrams with feynarts but his solution doesn't work for me.

Any other solutions?

    I recommend tikz-feynman instead. – Henri Menke Oct 25 '16 at 7:42
  • @HenriMenke I have tried tikz-feynman already and it's work!!! However, I get new problem about size of the diagram. I get very small diagram and small, medium and large don't work. – Natthawin Cho Oct 25 '16 at 12:50
  • I’m glad that my suggestion helped you. If you can extend your question by a short but compilable example illustrating your problem, I’ll be happy to provide you an answer. – Henri Menke Oct 25 '16 at 12:58
  • @HenriMenke First, I use \feynmandiagram[horizontal=a to b] and I found that the diagram is too small then I change to \feynmandiagram[large, horizontal=a to b]. However, nothing is changed. I also try the code in the manual which compare 3 size (small, medium, and large) but I also get the same size for 3 diagrams. – Natthawin Cho Oct 25 '16 at 13:01
