Minimal Massive 3D Gravity
read the original abstract
We present an alternative to Topologically Massive Gravity (TMG) with the same "minimal" bulk properties; i.e. a single local degree of freedom that is realized as a massive graviton in linearization about an anti-de Sitter (AdS) vacuum. However, in contrast to TMG, the new "minimal massive gravity" has both a positive energy graviton and positive central charges for the asymptotic AdS-boundary conformal algebra.

Minimal Massive Gravity Coupled to Higher Spins
Minimal Massive Gravity is coupled to a finite sl(N) tower of higher-spin fields, giving a Stückelberg formulation, AdS2 x S1 hair solutions, and two massive modes (spin j and j-2) for each spin-j > 2 field.

Chern-Simons-like formulation of 3D MMG-like massive gravity models
The simplest MMG-like third-way gravity model has unavoidable ghosts/tachyons, and at a chiral degenerate point its mass operator forms a rank-3 Jordan block, suggesting an ultra-logarithmic dual CFT.

A note on one-parameter subgroups of SO(3,2)
SO(3,2) one-parameter subgroups contain two new types, Id and V, with explicit coordinate transformations yielding new conformal gravity metrics.
