Holography of p p waves in conformal gravity

We consider holography of two pp-wave metrics in conformal gravity, their one-point functions, and asymptotic symmetries. One of the metrics is a generalization of the standard pp waves in Einstein gravity to conformal gravity. The holography of this metric shows that within conformal gravity one can have a realized solution which has a nonvanishing partially massless response tensor even for a vanishing subleading term in the Fefferman-Graham expansion (i.e., Neumann boundary conditions) and vice versa.
