First-order electroweak phase transition in a complex singlet model with symmetry
Cheng-Wei Chiang, Bo-Qiang Lu
We consider an extension of the Standard Model with a complex singlet scalar, where a global symmetry is explicitly broken to symmetry. We study the two-step…
Revisiting CP violation in and decays
Hai-Yang Cheng, Cheng-Wei Chiang
Direct CP violation in the hadronic charm decays provides a good testing ground for the Kobayashi-Maskawa mechanism in the Standard Model. Any significant deviations from the expec…
Displaced heavy neutrinos from decays at the LHC
Cheng-Wei Chiang, Giovanna Cottin, Arindam Das +1
We study the LHC sensitivity to probe a long-lived heavy neutrino in the context of models. We focus on displaced vertex signatures of when pair produced via a , d…
Thermal Loop Effects on Large-Scale Curvature Perturbation in the Higgs Inflation
Po-Wen Chang, Cheng-Wei Chiang, Kin-Wang Ng
It is known that the Higgs potential in the Standard Model can drive a successful inflation as long as the Higgs field couples non-minimally to gravity. It is then inevitable to ta…
A variant two-Higgs doublet model with a new Abelian gauge symmetry
Chuan-Ren Chen, Cheng-Wei Chiang, Kuo-Yen Lin
We consider a two-Higgs doublet model extended with a broken Abelian gauge symmetry under which all Standard Model (SM) quarks, fourth generation fermions and a new SM-singlet scal…
