Click For Summary
Quark diagrams serve as a specialized form of Feynman diagrams, focusing on interactions at the quark level, such as in beta decay. They simplify representations by omitting intermediate bosonic interactions, which can make analysis more straightforward. The use of quark diagrams adheres to Zweig's rule, suppressing diagrams with continuous gaps between quarks. This approach reduces complexity by limiting the number of gluons involved in the interactions. Overall, quark diagrams provide a clearer and more manageable framework for studying particle interactions.

Self-explaining question... Thanks.

As an alternative to Feynman diagrams (?), or so I heard...

It doesn't sound ok, right?

no then it just means a feynman diagram "on quark level" eg. beta decay

It seems reasonable... Thanks man

Maybe the double line formalism ?
 
I believe that they are a subclass of Feynman diagrams that do not show intermediate bosonic interactions; i.e. the relevant Feynman diagrams without any wiggly lines. The advantage is that any diagram with a continuous gap between the quarks is forbidden (suppressed) by Zweig's rule (iirc) and also that as flavour changing is relatively uncommon the lines often are just solid and 'simples'. Also, you don't have a whole infinity of gluons to worry about!
