Query: 4D spin-2 fields from 5D Chern-Simons theory   We consider a 5-dimensional Chern-Simons gauge theory for the isometry group
of Anti-de-Sitter spacetime,
$\operatorname{AdS}_{4+1}\simeq\operatorname{SO}(4,2)$, and invoke different
dimensional reduction schemes in order to relate it to 4-dimensional spin-2
theories. The AdS gauge algebra is isomorphic to a parametrized 4-dimensional
conformal algebra, and the gauge fields corresponding to the generators of
non-Abelian translations and special conformal transformations reduce to two
vierbein fields in $D=4$. Besides these two vierbeine, our reduction schemes
leave only the Lorentz spin connection as an additional dynamical field in the
4-dimensional theories. We identify the corresponding actions as particular
generalizations of Einstein-Cartan theory, conformal gravity and ghost-free
bimetric gravity in first-order form.
