Testing the custodial symmetry in the Higgs sector of the Georgi-Machacek model
Cheng-Wei Chiang, Kei Yagyu
We study how the custodial symmetry in the Higgs sector of the Georgi-Machacek (GM) model can be tested at the LHC. As the minimal extension of the Higgs triplet model, in which ti…
Higgs boson decays to and in models with Higgs extensions
Cheng-Wei Chiang, Kei Yagyu
The decays of a Higgs boson to the and final states are purely quantum mechanical phenomena that are closely related to each other. We study the effects of an extended Hi…
SU(3) symmetry breaking and CP violation in D -> PP decays
Hai-Yang Cheng, Cheng-Wei Chiang
Evidence of CP violation in the charm sector has been observed recently by the LHCb and CDF Collaborations. Adopting the topological diagram approach, we study flavor SU(3) symmetr…
Dark Matter and Higgs Boson in a Model with Discrete Gauge Symmetry
Cheng-Wei Chiang, Takaaki Nomura, Jusak Tandean
In view of ongoing measurements of the Higgs-like boson at the LHC and direct searches for dark matter, we explore the possibility of accommodating the potential results in a simpl…
Constraining Nonstandard Neutrino-Electron Interactions due to a New Light Spin-1 Boson
Cheng-Wei Chiang, Gaber Faisel, Yi-Fan Lin +1
We consider nonstandard interactions of neutrinos with electrons arising from a new light spin-1 particle with mass of tens of GeV or lower and couplings to the neutrinos and elect…
Direct CP violation in two-body hadronic charmed meson decays
Hai-Yang Cheng, Cheng-Wei Chiang
Motivated by the recent observation of CP violation in the charm sector by LHCb, we study direct CP asymmetries in the standard model (SM) for the singly Cabibbo-suppressed two-bod…
