boost converter transfer function

Did anyone know why the buck dc converter has a left-hand zero but the boost has a right-hand zero?Can supply some material about this topic?
Thank you!
 

boost transfer function

If you are talking about voltage mode, I think the zero of the buck DCDC converter comes from the ESR of the LC filter.

I think right-plane zero in a boost converter is related to continuous or discontinuous mode of operation.
