abstract
We perform a complete decoupling of the degrees of freedom of quadratic gravity and the generic $f (R_{\mu\nu\sigma \rho})$ theory about any one of their possible vacua, i.e. maximally symmetric solution, find the masses of the spin-2 and spin-0 modes in explicit forms.

Non-Fierz-Pauli bimetric theory from quadratic curvature gravity on Einstein manifolds
Quadratic curvature gravity on Einstein manifolds decouples into massless and non-Fierz-Pauli massive gravity sectors, enabling observational constraints on its parameters with noted tension for the Weyl term.
