Drawing Feynman diagrams with feynarts

  1. Nov 13, 2015 #1
    I'm trying to draw Feynman diagrams with the feynarts.sty package for LaTex. The problem is that if I write the following code

    \begin{feynartspicture}(150,150)(1,1)
    \FADiagram{}
    \FAProp(0.,10.)(6.,10.)(0.,){/Straight}{0}
    \FALabel(3.,9.18)[t]{$1$}
    \FAProp(20.,10.)(14.,10.)(0.,){/Straight}{0}
    \FALabel(17.,10.82){$2$}
    \FAProp(6.,10.)(14.,10.)(0.8,){/Straight}{0}
    \FALabel(10.,5.98)[t]{$3$}
    \FAProp(6.,10.)(14.,10.)(-0.8,){/Straight}{0}
    \FALabel(10.,14.02){$4$}
    \FAVert(6.,10.){0}
    \FAVert(14.,10.){0}
    \end{feynartspicture}

    I get this

    instead of this

    how can I fix this?

    How did you compile the file and what output did you look at?

    I found the solution. I need to compile following the latex -> dvips -> ps2pdf sequence. This can be made in TexShop putting the command

    %!TEX TS-program = latex

    in the first line of the tex file.
