Standard Model Mass Spectrum in Inflationary Universe
Xingang Chen, Yi Wang, Zhong-Zhi Xianyu
We work out the Standard Model (SM) mass spectrum during inflation with quantum corrections, and explore its observable consequences in the squeezed limit of non-Gaussianity. Both…
Standard Model Background of the Cosmological Collider
Xingang Chen, Yi Wang, Zhong-Zhi Xianyu
The inflationary universe can be viewed as a "Cosmological Collider" with energy of Hubble scale, producing very massive particles and recording their characteristic signals in pri…
Cosmic Decoherence: Massive Fields
Junyu Liu, Chon-Man Sou, Yi Wang
We study the decoherence of massive fields during inflation based on the Zurek's density matrix approach. With the cubic interaction between inflaton and massive fields, the reduce…
Loop Corrections to Standard Model Fields in Inflation
Xingang Chen, Yi Wang, Zhong-Zhi Xianyu
We calculate 1-loop corrections to the Schwinger-Keldysh propagators of Standard-Model-like fields of spin-0, 1/2, and 1, with all renormalizable interactions during inflation. We…
Fluctuations in a Cosmology with a Space-Like Singularity and their Gauge Theory Dual Description
Robert H. Brandenberger, Yi-Fu Cai, Sumit R. Das +3
We consider a time-dependent deformation of anti-de-Sitter (AdS) space-time which contains a cosmological "singularity" - a space-like region of high curvature. Making use of the A…
Probing the Primordial Universe using Massive Fields
Xingang Chen, Mohammad Hossein Namjoo, Yi Wang
Inflation models are numerous. It is extremely difficult, if possible at all, to identify the actual underlying inflation model of our primordial universe. Thus, for the purpose of…
