摘要: In this work, we explain the 750 GeV diphoton resonance in the Next to Minimal Supersymmetric Standard Model (NMSSM) by introducing vector-like particles. Such an extension is well motivated from the top-down view since some grand unified theories usually

摘要: In this paper, we interpret the 750 GeV diphoton excess in the Zee–Babu extension of the two-Higgs-doublet model by introducing a top partner ( T )/bottom partner ( B ). In the alignment limit, the 750 GeV resonance is identified as the heavy CP-even Higg

摘要: In this paper we simultaneously explain the excesses of the 750 GeV diphoton, muon g-2 and h→μτ in an extension of the two-Higgs-doublet model (2HDM) with additional vector-like fermions and a CP-odd scalar singlet ( P ) which is identified as the 750 GeV

摘要: 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

摘要: In this note we revisit the SUSY effects in Rb under current experimental constraints including the LHC Higgs data, the B -physics measurements, the dark matter relic density and direct detection limits, as well as the precision electroweak data. We first

摘要: A radiative natural SUSY spectrum are proposed in the deflected anomaly mediation scenario with general messenger-matter interactions. Due to the contributions from the new interactions, positive slepton masses as well as a large |Att_{t} | term can natur

摘要: We utilize the recent LHC-13 TeV data to study the lower mass bound on top-squark (stop) in natural supersymmetry. We recast the LHC sparticle inclusive search of (≥1)jets+EmissT(≥1)jets+ETmiss(\ge 1){\rm jets} + E^{miss}_T with αTαT\alpha_T variable, the

摘要: We study the excesses of R(D(?))R(D(?))R(D^{(*)}) and muon g?2g?2g-2 in the framework of a two-Higgs-doublet model with top quark flavor-changing neutral-current (FCNC) couplings. Considering the relevant theoretical and experimental constraints, we find

摘要: Top squark (stop) can be produced via QCD interaction but also the electroweak interaction at the LHC. In this paper, we investigate the observability of the associated production of stop and chargino, pp→t~1χ~?1pp→t~1χ~1?pp \to \tilde{t}_1\tilde{\chi}^-_

摘要: Motivated by the latest results of the LHC Run-2 and LUX experiments, we examine the status of the constrained minimal supersymmetric standard model (CMSSM) by performing a global fit. We construct a likelihood function including the electroweak precision
