Probing Light Higgsinos in Natural SUSY from Monojet Signals at the LHC
Han,C; Kobakhidze,A; Liu,N; Saavedra,A; Wu,L; Yang,JM
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 μμ\mu in 100?150100?150100-150 GeV, which is preferred by the naturalness, can be probed at 2σ2σ2\si |
ATLAS Z-peaked excess in the MSSM with a light sbottom or stop
Kobakhidze,A; Liu,N; Wu,L; Yang,JM
We attempt to explain the recent ATLAS 3σ excess of dilepton events with an invariant mass near Z peak through the gluino-mediated sbottom production in a simplified scenario inspired by the minimal supersymmetric Standard Model. The additional Z bosons c |
Closing up a light stop window in natural SUSY at LHC
Kobakhidze,A; Liu,N; Wu,L; Yang,JM; Zhang,M
Top squark (stop) plays a key role in the radiative stability of the Higgs boson mass in supersymmetry (SUSY). In this work, we use the LHC Run-1 data to determine the lower mass limit of the right-handed stop in a natural SUSY scenario, where the higgsin |
750 GeV diphoton resonance in a top and bottom seesaw model
Kobakhidze,A; Wang,F; Wu,L; Yang,JM; Zhang,M
The top and bottom seesaw model, which extends the top seesaw in order to accommodate a 125 GeV Higgs boson, predicts vector-like top/bottom partners and these partners can be bounded to form several neutral and charged singlet composite scalars by some n |
