Nano-Hertz gravitational waves from collapsing domain walls associated with freeze-in dark matter in light of pulsar timing array observations
Zhao Zhang, Chengfeng Cai, Yu-Hang Su +3
Evidence for a stochastic gravitational wave background in the nHz frequency band is recently reported by four pulsar timing array collaborations NANOGrav, EPTA, CPTA, and PPTA. It…
Searching for Heavy Dark Matter near the Planck Mass with XENON1T
E. Aprile, K. Abe, S. Ahmed Maouloud +164
Multiple viable theoretical models predict heavy dark matter particles with a mass close to the Planck mass, a range relatively unexplored by current experimental measurements. We…
Freeze-in Production of Pseudo-Nambu-Goldstone Dark Matter Model with a Real Scalar
Xue-Min Jiang, Chengfeng Cai, Yu-Hang Su +1
In this work, we study a pseudo-Nambu-Goldstone boson (pNGB) dark matter model extended with a real scalar. The dark sector is assumed to be feebly coupled with the standard model…
