MG5_aMC>generate w+ > c b~
INFO: Trying process: w+ > c b~ @1
Command "generate w+ > c b~" interrupted with error:
NoDiagramException : No amplitudes generated from process Process: w+ > c b~ @1. Please enter a valid process

is it not implemented in madgraph?

which model are you using?
probably your model that you are using doesn't have CKM matrix fully implemented

Can you help with this problem?
