A massive graviton in topologically new massive gravity [PDF]
Yong-Wan Kim, Yun Soo Myung, Young-Jai ParkWe investigate the topologically new massive gravity in three dimensions. It turns out that a single massive mode is propagating in the flat spacetime, comparing to the conformal Chern-Simons gravity which has no physically propagating degrees of freedom. Also we discuss the realization of the BMS/GCA correspondence.View original: http://arxiv.org/abs/1301.0969
