Near horizon linearized gravity and soft theorem
Pujian Mao, Kai-Yu Zhang, Bochen Zhou
In this paper, we study the linearized gravity theory in the near horizon region of the Schwarzschild black hole in four dimensional spacetime. Under the Newman-Unti gauge, we deri…
Soft theorems in de Sitter spacetime
Pujian Mao, Kai-Yu Zhang
In this paper, we derive a soft photon theorem and a soft gluon theorem in the de Sitter spacetime from the Ward identity of the near cosmological horizon large gauge transformatio…
Explaining the boson mass anomaly and dark matter with a dark sector
Kai-Yu Zhang, Wan-Zhe Feng
The boson mass recently reported by the CDF collaboration shows a deviation from the standard model prediction with an excess at level. We investigate two simple extension…
Oscillating universe in massive gravity
Kaituo Zhang, Puxun Wu, Hongwei Yu
Massive gravity is a modified theory of general relativity. In this paper, we study, using a method in which the scale factor changes as a particle in a "potential", all possible c…
