Feynman diagrams for Δ++ and Ξ- decay

[jaoc]

Homework Statement

Would appreciate help with Feynman Diagrams for these two decays:
1.- DELTA ++ into proton + PI 0
Δ ++ → p + π0
2.- XSI - into SIGMA 0 + PI minus
Ξ - → Λ0 + π-

Relevant Equations

Δ ++ → p + π0
Ξ - → Λ0 + π-

Δ ++ → p + π0
Ξ - → Λ0 + π-

First you need to show some effort, first of all, have you done a quick analysis to see if these decays are possible?

To add to what Gaussian97 said, start with the quark content of all these particles.

For the process 1, I can get Feynman diagram but with a pi_+, not with a pi_0

For the process 2, I am not sure abt file attached (right figure)

Thanks again
