Title: Partition function in Weyl conformal gravity

Abstract: We derive the form of the partition function in conformal
gravity using an extended form of the Faddeev-Popov method for two
distinct families of gauges. The method uses conformal gauge fixings and
special conformal ghosts. First, the case of simple covariant fixing and
later the gauge proposed by Horowitz, Perry, and Strominger will be
reviewed. In this way, at one-loop, the theory is proven to be
regularized in a conformally invariant way also on the quantum level
without performing an additional final conformal transformation. The
partition function is discussed on a general background as well as on
Ricci-flat, maximally symmetric and Einstein spaces.
