The successful background-independent quantization of loop quantum gravity (LQG) relies on the key observation that classical general relativity (GR) can be cast into the connection-dynamical formalism with the structure group of $SU(2)$.Due to this particular formalism,LQG was generally considered as a quantization scheme that applies only to GR.Our work shows that the nonperturbative quantization procedure of LQG can be extended to a rather general class of 4-dimensional metric theories of gravity,which have received increased attention recently due to motivations coming form cosmology and astrophysics.
