Chiral enhancement in the vector-like fourth family: Case of
Junichiro Kawamura, Yuji Omura
We demonstrate that a vector-like fourth family of quarks induces a genuine chiral enhancement in , which is absent in the Standard Model (SM). The coexistence of doublet…

96 GeV Scalar Boson in the 2HDM with U(1)_H Gauge Symmetry
Seungwon Baek, P. Ko, Yuji Omura +1
In this paper, we study two Higgs doublet models with gauged U(1)_H symmetry, motivated by the excesses around 96 GeV reported by the CMS collaboration in the searches for light re…
