Hidden SU(2)_D vector dark matter with a scalar septuplet

Zhao Zhang, Chengfeng Cai, Hong-Hao Zhang

We propose a vector dark matter model from a hidden SU(2)_D gauge symmetry at TeV scale. A scalar septuplet is introduced to break the SU(2)_D symmetry spontaneously. The septuplet…

Ultraviolet completion of pseudo-Nambu-Goldstone dark matter with a hidden U(1) gauge symmetry

Dan-Yang Liu, Chengfeng Cai, Xue-Min Jiang +2

We propose an ultraviolet completion model for pseudo-Nambu-Goldstone dark matter with a hidden gauge symmetry. Compared to previous studies, this setup is simpler,…

Corrections to electroweak precision observables from mixings of an exotic vector boson in light of the CDF -mass anomaly

Chengfeng Cai, Dayun Qiu, Yi-Lei Tang +2

We enumerate various effective couplings that contribute to the mixings between an exotic vector boson and the neutral electroweak vector bosons. The miscellaneous mix…
