    I'm trying to convert a section of my notes into Latex. Mostly it's fine but in the last lecture the lecturer used some notation I cannot seem to do.

    I want to do the braces over the phi's in this picture


    Unfortunately I can't find any way of doing it. Overline and curved brackets don't allow for the "interlinking" the notation requires, and don't look like the notation anyway.

    Also, is there a simple way to do the diagrams shown


    I tried doing the standard Feynman diagram method involving metafiles but it doesn't allow me to label any vertices or lines.

    /edit

    Remembered another one. I can't seem to do a strike through letters, just like \not= has a strike through the equals sign. Putting "\not" before symbols works fine, but not through letters. I can get \not{a} but its not the same as the symbol used in question 9 here.

    /edit again

    Okay, it seems to work on these forums, but when I put "\not{a}" in latex programs it doesn't work properly.

    Any help would be much appreciated (ie rep points)

    well, I think you should use graphic and add it to your note , use \includegraphics[key= ]{file} or maybe there are some other ways of doing it
    However I've never used it.
    Or you can draw it by your own hands :p:

    I know how to add jpegs I've made in other programs or scanned in but they lack the "seamless" look I'm after. There must be a native way of doing these things in Latex

    You could draw the lines in a drawing package such as illustrator (not photoshop), together with placeholder text where the phis should go:

    A B C D E F G H

    Export the picture as an eps file. Use \includegraphics to add the eps in your latex file, and psfrag commands to change the placeholders into phis:

    \psfrag{A}{$\phi_1$}
    \psfrag{B}{$\phi_2$}
    ...

    To tweak the spacing, say

    \psfrag{A}{\raise-2mm\hbox{\kern1mm\hbox{$\phi_1$} }}
    ...
