Interpreting the KM3-230213A PeV Neutrino Event via Vector Dark Matter Decay and Its Multi-Messenger Signatures
Yu-Hang Su, Si-Yu Chen, Chengfeng Cai +1
The KM3NeT Collaboration recently reported the detection of an ultra-high-energy neutrino event KM3-230213A with a reconstructed energy of PeV, the most energet…
Constraining the Secluded and Catalyzed Annihilation Dark Matter with Fermi-LAT and Planck Data
Yu-Hang Su, Chengfeng Cai, Hong-Hao Zhang
We propose a dark matter (DM) model with a complex scalar charged under a hidden gauge symmetry, denoted as . The scalar field is the DM candidate while the gauge…
Complex scalar dark matter in a new gauged U(1) symmetry with kinetic and direct mixings
Yu-Hang Su, Chengfeng Cai, Yu-Pan Zeng +1
We propose a scalar dark matter model featuring a hidden gauge symmetry, denoted as U(1)_X, with two complex scalars, Phi and S. In this framework, Phi spontaneously breaks the U(1…
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…
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…
