Cosmological Signatures of Superheavy Dark Matter
Lingfeng Li, Shiyun Lu, Yi Wang +1
We discuss two possible scenarios, namely the curvaton mechanism and the dark matter density modulation, where non-Gaussianity signals of superheavy dark matter produced by gravity…

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…

Neutrino Signatures in Primordial Non-Gaussianities
Xingang Chen, Yi Wang, Zhong-Zhi Xianyu
We study the cosmological collider phenomenology of neutrinos in an effective field theory. The mass spectrum of neutrinos and their characteristic oscillatory signatures in the sq…
