Two Higgs doublet models with local U(1)_H gauge symmetry and dark matter
P. Ko, Yuji Omura, Chaehyun Yu
We propose to implement the softly broken Z_2 symmetry in the usual two Higgs doublet model (2HDM) to spontaneously broken local U(1)_H gauge symmetry, and show that the resulting…

Correlation of top asymmetries: loop versus tree origins
Sunghoon Jung, P. Ko, Yeo Woong Yoon +1
We study the correlation of top asymmetries that are sensitive to the different origin of (a new contribution to) the total asymmetry: loop- or tree-level origins. We find that bot…

Multi-Higgs doublet models with local gauge symmetry and neutrino physics therein
P. Ko, Yuji Omura, Chaehyun Yu
Multi-Higgs doublet models appear in many interesting extensions of the standard model (SM). But they suffer from Higgs-mediated flavor changing neutral current (FCNC) problem whic…
