Probing the Axion-Photon-Dark Photon Interaction at Future Colliders
Chuan-Ren Chen, Yuan-Feng Hsieh, Van Que Tran
We study the interaction between photons, dark photons, and axions at future lepton colliders, focusing on single-photon events with missing energy as the experimental signature. W…
Search for Long-Lived Dark Photons from Dark Radiation at the LHC
Chuan-Ren Chen, Van Que Tran
We investigate a novel production mechanism for long-lived dark photons at the LHC, arising from dark radiation emitted from in decays, where is a fermioni…
TeV-scale unification of light dark matter and neutrino mass
Cheng-Wei Chiang, Shu-Yu Ho, Van Que Tran
We demonstrate that TeV-scale heavy neutral leptons (HNLs) responsible for inverse-seesaw neutrino mass generation can simultaneously fix the cosmological abundance and decay prope…
Current Status of Inert Higgs Dark Matter with Dark Fermions
Yi-Zhong Fan, Yao-Yu Li, Chih-Ting Lu +4
The precision measurements of the muon magnetic moment and the boson mass have sparked interest in the potential deviations from standard model (SM) predictions. While it may b…
Freeze-in Production of Non-Abelian Millicharged Vector Dark Matter
Van Que Tran, Tzu-Chiang Yuan
We present the first predictive realization, to our knowledge, of vector freeze-in dark matter from a hidden non-Abelian gauge sector spontaneously broken by a Higgs triple…
Tri-hypercharge versus tri-darkcharge
Duong Van Loi, A. E. Cárcamo Hernández, Van Que Tran +1
We propose a minimal, ultraviolet-complete, and renormalizable extension of the Standard Model, in which the three generations of ordinary fermions are distinguished by family-depe…
