Higgs potential and hidden light Higgs scenario in two Higgs doublet models
Sanghyeon Chang, Sin Kyu Kang, Jong-Phil Lee +1
In two Higgs doublet models (2HDM), there exists an interesting possibility, the hidden light Higgs scenario, that the discovered SM-like Higgs boson is the heavier \textit{CP}-eve…
Two Higgs doublet models for the LHC Higgs boson data at 7 and 8 TeV
Sanghyeon Chang, Sin Kyu Kang, Jong-Phil Lee +3
Updated LHC data on the new 126 GeV boson during the 7 and 8 TeV runnings strengthen the standard model Higgs boson interpretation further. Through the global analysis, we in…
Comprehensive study of two Higgs doublet model in light of the new boson with mass around 125 GeV
Sanghyeon Chang, Sin Kyu Kang, Jong-Phil Lee +3
The recent discovery of a new boson of mass roughly 125 GeV has been reported by the ATLAS and CMS collaborations. Although its signals in various decay modes resemble those of the…
Direct bound on the minimal Universal Extra Dimension model from the resonance search at the Tevatron
Sanghyeon Chang, Kang Young Lee, So Young Shim +1
In the minimal Universal Extra Dimension (mUED) model, the second Kaluza-Klein (KK) gluon has loop-induced vertices with the standard model quarks, mediated by the first…
Implications on the mUED model from the early LHC data on $\ell+\met$ signal
Sanghyeon Chang, Kang Young Lee, Jeonghyeon Song
Recently the ATLAS and CMS collaborations reported their search for a new heavy gauge boson with one lepton plus missing transverse momentum. We find that , the secon…
Probing axino LSP from diphotons events with large missing transverse energy
Sanghyeon Chang, Kang Young Lee, Jeonghyeon Song
In a supersymmetry model with an axino as the lightest supersymmetric particle (LSP) and a Bino as the next LSP (NLSP), supersymmetry particles produced in pair at a high energy co…
