Superheavy Dark Matter Production from Symmetry Restoration First-Order Phase Transition During Inflation
Haipeng An, Xi Tong, Siyi Zhou
We propose a scenario where superheavy dark matter (DM) can be produced via symmetry restoration first-order phase transition during inflation triggered by the evolution of the inf…

Large Spin-2 Signals at the Cosmological Collider
Xi Tong, Zhong-Zhi Xianyu
We study the theory and phenomenology of massive spin-2 fields during the inflation with nonzero background chemical potential, and extend the cosmological collider physics to tens…

Probing P and CP Violations on the Cosmological Collider
Tao Liu, Xi Tong, Yi Wang +1
In direct analogy to the 4-body decay of a heavy scalar particle, the 4-point correlation function of primordial fluctuations carries P and CP information. The CP violation appears…
