Graviton energy spectra arising from the KSVZ axion model
Yonghua Wang, Lin-Yun He, Wei Chao +1
Axion, the goldstone boson arising from the spontaneous breaking of a global Peccei-Quinn symmetry, provides a dynamical solution to the strong CP problem and is an excellen…

Testing the type-II seesaw mechanism with gravitational waves
Yonghua Wang, Wei Chao
Traditional seesaw mechanisms provide an elegant theoretical framework for explaining the small yet non-zero masses of neutrinos. Nevertheless, they face significant experimental c…

Gravitational Wave Spectrum from the Production of Dark Matter via the freeze-in Mechanism
Yonghua Wang, Wei Chao
Since the first detection of gravitational waves by ground-based interferometers, it has emerged as a novel probe for exploring physics in the early universe. The particle nature o…
