Hi,(adsbygoogle = window.adsbygoogle || []).push({});

My question is that can one interaction term represent two vertices?

For instance, can the lagrangian interaction terms L = eψγ^{μ}ψA_{μ}represent a feynman diagram like these:

or should there be two terms in the lagrangian to construct such diagrams?

Thanks!
