Hello, I'm a bit unclear on how the EM, weak, and strong forces can change the flavor of a quark. EM/Weak Force: Can you skip a generation (ie. u -> t or b -> d)? Also can you change quark generations with a W (ie, while also changing the quark charge, e.g. u -> s)? Strong force: Can the strong force change the type of quark, and if so, what are the rules for this?
