A light SUSY dark matter after CDMS-II, LUX and LHC Higgs data
Junjie Cao, Chengcheng Han, Lei Wu +2
In SUSY, a light dark matter is usually accompanied by light scalars to achieve the correct relic density, which opens new decay channels of the SM like Higgs boson. Under current…
Probing Light Higgsinos in Natural SUSY from Monojet Signals at the LHC
Chengcheng Han, Archil Kobakhidze, Ning Liu +3
We investigate a strategy to search for light, nearly degenerate higgsinos within the natural MSSM at the LHC. We demonstrate that the higgsino mass range in GeV, whi…
A light Higgs scalar in the NMSSM confronted with the latest LHC Higgs data
Junjie Cao, Fangfang Ding, Chengcheng Han +2
In the Next-to-Minimal Supersymemtric Standard Model (NMSSM), one of the neutral Higgs scalars (CP-even or CP-odd) may be lighter than half of the SM-like Higgs boson. In this case…
Current experimental bounds on stop mass in natural SUSY
Chengcheng Han, Ken-ichi Hikasa, Lei Wu +2
Motivated by the recent progress of direct search for the productions of stop pair and sbottom pair at the LHC, we examine the constraints of the search results on the stop ($\tild…
Higgs pair production with SUSY QCD correction: revisited under current experimental constraints
Chengcheng Han, Xuanting Ji, Lei Wu +2
We consider the current experimental constraints on the parameter space of the MSSM and NMSSM. Then in the allowed parameter space we examine the Higgs pair production at the 14 Te…
Natural SUSY from SU(5) Orbifold GUT
Chengcheng Han, Fei Wang, Jin Min Yang
We propose a realistic 5D orbifold GUT model that can reduce to natural (or radiative natural) supersymmetry as the low energy effective theory. Supersymmetry as well as gauge symm…
