Hi. I read this post about drawing Feynman diagrams using trees and decoration http://www.texample.net/tikz/examples/feynman-diagram/

I was wondering if anyone could explain/show me how to use this technique to draw the following two diagrams (known as t and u channel gluon fusion):

Hi and welcome,

it seems like your image got lost. Can you post it again?
It would also be nice to show us what you tried so far to achieve the result. Makes it easier to help with a good starting point.

Hey Johannes, thanks for your reply. To be honest my attempt is all but non-existent. Latex is new to me (recently learnt it to write up my thesis) so I've basically got no idea how to go about drawing these diagrams

Welcome to the forum!

You are new to LaTeX, nice! Still a lot to learn I guess. I just doesn't mean that people do complete work for you.

Though we are glad to help. We also don't repeat manuals. The

TikZ manual is very comprehensive, that's obvious, but it provides tutorials and a reference. You could take the example from the TeXample web site, take the TikZ manual and try to understand what it writes about the used commands from that example. Then try to modify the example code so it matches your requirement. If you like to use TikZ for several drawings, you need to learn a bit anyway.

If you got questions in this process, or something doesn't work, you can always ask us. I just don't have time to do a complete drawing myself and to explain what is written in the manual with other words. But no problem to answer specific problems or to help correcting or improving a drawing.

That's true, I was being a little cheeky. I'll have a look and ask a question or two as needed.

For anyone interested, I ended up using this http://feynman.aivazis.com/. Very easy!
