On the uniqueness of ghost-free special gravity
Dong Bai, Yu-Hang Xing
Special gravity refers to interacting theories of massless gravitons in Minkowski space-time which are invariant under the abelian gauge invariance $h_{ab}\rightarrow h_{ab}+\parti…
More on the Bending of Light in Quantum Gravity
Dong Bai, Yue Huang
We reconsider the long-range effects of the scattering of massless scalars and photons from a massive scalar object in quantum gravity. At the one-loop level, the relevant quantum…
Higher Derivative Theories for Interacting Massless Gravitons in Minkowski Spacetime
Dong Bai, Yu-Hang Xing
We study a novel class of higher derivative theories for interacting massless gravitons in Minkowski spacetime. These theories were first discussed by Wald decades ago, and are cha…
Softness, Polynomial Boundedness and Amplitudes' Positivity
Dong Bai
In this note, we study the connections between infrared (IR) and ultraviolet (UV) behaviors of scattering amplitudes of massless channels by exploiting dispersion relations and pos…
