Abstract： Motivated by the recent LHC hints of a Higgs boson around 125 GeV, we assume a SM-like Higgs with the mass 123-127 GeV and study its implication in low energy SUSY by comparing the MSSM and NMSSM. We consider various experimental constraints at 2-sigma le

Abstract： We consider the natural supersymmetry scenario in the framework of the R-parity conserving minimal supersymmetric standard model (called natural MSSM) and examine the observability of stop pair production at the LHC. We first scan the parameters of this s

Abstract： The excess of top quark forward-backward asymmetry (AtFBAFBtA^t_{FB}) reported by the Tevatron and the enhancement of the Higgs decay to diphoton observed by the LHC may point to a same origin of new physics. In this note we examined such anomalies in the

Abstract： 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 (t~1t~1\tilde{t}_1) mass in natural SUSY. We first scan the parameter space of nat

Abstract： In some supersymmetric models like split supersymmetry or models with nonuniversal gaugino mass, ‘bino [lightest sparticle (LSP)] and wino [next-to-lightest sparticle (NLSP)] may have rather small mass splitting in order to provide the correct dark matter

Abstract： Considering the constraints from collider experiments and dark matter detection, we investigate the SUSY effects in the Higgs production channels e(+) e(?) → Zh at an e(+) e(?) collider with a center-of-mass energy above 240 GeV and γγ → h → bb? at a phot

Abstract： We explore the explanation of the Fermi Galactic Center excess (GCE) in the next-to-minimal supersymmetric Standard Model. We systematically consider various experimental constraints including the dark matter (DM) relic density, DM direct detection result

Abstract： Recently the ATLAS collaboration reported a 3σ excess in the leptonic-Z + jets + EmissTTmiss_{T}^{miss} channel. This may be interpreted in the Next-to-Minimal Supersymmetric Standard Model (NMSSM) by gluino pair production with the decay chain g~→qq??χ~0

Abstract： We propose a deflected anomaly mediation scenario from SUSY QCD which can lead to both positive and negative deflection parameters (there is a smooth transition between these two deflection parameter regions by adjusting certain couplings). Such a scenari

Abstract： In the Next-to-Minimal Supersymmetric Standard Model (NMSSM), all singlet-dominated particles including one neutralino, one CP-odd Higgs boson and one CP-even Higgs boson can be simultaneously lighter than about 100 GeV. Consequently, dark matter (DM) in

Abstract： The ATLAS collaboration recently reported a 3σ excess in the leptonic-Z + jets + EmissTTmiss_{T}^{miss} channel. We intend to interpret this excess by squark pair production in the Next-to-Minimal Supersymmetric Standard Model (NMSSM). The decay chain we

Abstract： The evidence of a new scalar particle X from the 750 GeV diphoton excess, and the absence of any other signal of new physics at the LHC so far suggest the existence of new colored scalars, which may be moderately light and thus can induce sizable Xgg and

Abstract： In the simplest Higgs-portal scalar dark matter model, the dark matter mass has been restricted to be either near the resonant mass ( mh/2 ) or in a large-mass region by the direct detection at LHC Run 1 and LUX. While the large-mass region below roughly
