Feynman diagrams strong process

Summary:

Write the Feynman diagram for a strong scattering
Hello everybody!

I have to write the Feynman diagrams for the process ##\pi^- + p \rightarrow \Lambda_c^+ + D^-##. It is a strong process since all the quantum numbers are conserved.
I have attached my attempt, is it correct?

Thank you all in advance!

It is not wrong, but I would probably not give it much credit. (And since this looks like homework, I don't want to say more.)

Thank you for the reply. The attached diagram is better? The previous diagram is ##\mathcal{O}(\alpha_s^2)##, instead this one is ##\mathcal{O}(\alpha_s)##, isn't it?

PS It is not homework, I was just discussing about Feynman diagrams with a mate of mine.

Sure does look better...but the rule here is for homework-like problems. Even if they are really a bar bet.
