Quark masses and mixing in the D_5 model under spontaneous CP violation
Dong-Ping Fu, Michihisa Takeuchi
It is known that CP violation occurs in flavor physics, and the CKM matrix is complex. We investigate the Yukawa sector of a four-Higgs model based on D_5 symmetry. To understand a…

Ye Cao, Cheng Chen, Dongyan Fu +1
We present a systematic study of the spacelike electromagnetic form factors of the ground-state singly charmed baryons, () and , within a covaria…
A D_5 Model of Quarks with Explicit CP Violation
Dong-Ping Fu, Michihisa Takeuchi
We investigate the quark sector of a four-Higgs-doublet model with an exact D_5 symmetry. In the framework of explicit CP violation, we considered the most general real vacuum, der…
