Phase transition gravitational waves from pseudo-Nambu-Goldstone dark matter and two Higgs doublets

no code implementations2 Feb 2021 Zhao Zhang, Chengfeng Cai, Xue-Min Jiang, Yi-Lei Tang, Zhao-Huan Yu, Hong-Hao Zhang

We investigate the potential stochastic gravitational waves from first-order electroweak phase transitions in a model with pseudo-Nambu-Goldstone dark matter and two Higgs doublets.

Inert sextuplet scalar dark matter at the LHC and future colliders

no code implementations16 Aug 2020 Dan-Yang Liu, Chengfeng Cai, Zhao-Huan Yu, Yu-Pan Zeng, Hong-Hao Zhang

We study a dark matter model constructed by extending the standard model with an inert $\mathrm{SU}(2)_\mathrm{L}$ sextuplet scalar of hypercharge 1/2.
