Further study of the global minimum constraint on the two-Higgs-doublet models: LHC searches for heavy Higgs bosons
/ Chen, Ning ; Du, Chun ; Wu, Yongcheng ; Xu, Xun-Jie
The usually considered vacuum of the two-Higgs-doublet model (2HDM) could be unstable if it locates at a local but not global minimum (GM) of the scalar potential. [...]

Measuring the CP property of Higgs coupling to tau leptons in the VBF channel at the LHC
/ Han, Tao ; Mukhopadhyay, Satyanarayan ; Mukhopadhyaya, Biswarup ; Wu, Yongcheng

Unblinding the dark matter blind spots
/ Han, Tao ; Kling, Felix ; Su, Shufang ; Wu, Yongcheng
The dark matter (DM) blind spots in the Minimal Supersymmetric Standard Model (MSSM) refer to the parameter regions where the couplings of the DM particles to the Z -boson or the Higgs boson are almost zero, leading to vanishingly small signals for the DM direct detections. [...]
