Dual Gravitational Wave Signatures of Instant Preheating
Wei-Yu Hu, Kazunori Nakayama, Volodymyr Takhistov +1
In the instant preheating scenario efficient particle production occurs immediately following the period of inflationary expansion in the early Universe. We demonstrate that instan…
Linear dynamics and classical tests of the gravitational quantum field theory
Yuan-Kun Gao, Da Huang, Yong-Liang Ma +3
We explore the new physics phenomena of gravidynamics governed by the inhomogeneous spin gauge symmetry based on the gravitational quantum field theory. Such a gravidynamics enable…
Gravitational Wave Probe of Planck-scale Physics After Inflation
Weiyu Hu, Kazunori Nakayama, Volodymyr Takhistov +1
Particle decays are always accompanied by the emission of graviton quanta of gravity through bremsstrahlung processes. However, the corresponding branching ratio is suppressed by t…
Residual Non-Abelian Dark Matter and Dark Radiation
P. Ko, Yong Tang
We propose a novel particle physics model in which vector dark matter (VDM) and dark radiation (DR) originate from the same non-Abelian dark sector. We show an illustrating example…
Light dark photon and fermionic dark radiation for the Hubble constant and the structure formation
P. Ko, Yong Tang
Motivated by the tensions in the Hubble constant and the structure growth between results and other low redshift measurements, we discuss some cosmological eff…
Higgs-Portal Dark Matter for GeV Gamma-Ray Excess
P. Ko, Wan-Il Park, Yong Tang
We present Higgs-Portal dark matter (DM) models to explain the reported Galactic Center GeV gamma-ray excess. Naive effective theories are inconsistent with direct detection constr…
