# Decay Feynman Diagrams

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?

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
