“…Specific searches for higgsinos have been performed by ATLAS [72, 76, 78] and CMS [85] assuming a lightest SUSY particle (LSP) in the form of a massless gravitino [85], or the presence of a light stau [76,78] or light sleptons [78]. Apart from these specific scenarios, light higgsinos are thus hardly constrained by searches at the run I of the LHC, see the analyses within phenomenologically viable versions of the MSSM or NMSSM in [33,[94][95][96][97][98][99][100][101][102][103][104][105][106][107][108][109].…”

Abstract:The light higgsino-singlino scenario of the NMSSM allows to combine a naturally small µ parameter with a good dark matter relic density. Given the new constraints on spin-dependent and spin-independent direct detection cross sections in 2016 we study first which regions in the plane of chargino-and LSP-masses below 300 GeV remain viable. Subsequently we investigate the impact of searches for charginos and neutralinos at the LHC, and find that the limits from run I do not rule out any additional region in this plane. Only the HL-LHC at 3000 fb −1 will test parts of this plane corresponding to higgsino-like charginos heavier than 150 GeV and relatively light singlinos, but notably the most natural regions with lighter charginos seem to remain unexplored.

We explored the sparticle mass spectrum in light of the muon g − 2 anomaly and the little hierarchy problem in a class of gauge mediated supersymmetry breaking model. Here the messenger fields transform in the adjoint representation of the Standard Model gauge symmetry. To avoid unacceptably light right-handed slepton masses the standard model is supplemented by additional U (1) B−L gauge symmetry. Considering a non-zero U (1) B−L D-term leads to an additional contribution to the soft supersymmetry breaking mass terms which makes the right-handed slepton masses compatible with the current experimental bounds. We show that in the framework of Λ 3 < 0 and µ < 0, the muon g − 2 anomaly and the observed 125 GeV Higgs boson mass a can be simultaneously accommodated. The slepton masses in this case are predicted to lie in the few hundred GeV range, which can be tested at LHC. Despite the heavy colored spectrum the the little hierarchy problem in this model can be ameliorated and electroweak fine tuning parameter can be as low as 10 or so.

“…The minimal supersymmetric standard model (MSSM) not only provides an elegant solution to the hierarchy problem but also may successfully explain the (g − 2) µ anomaly [2,3,4,5,6,7,8,9,10]. The recently measured value for ∆a are more than 3σ away from the SM prediction, which includes improved QED [14] and electroweak [15] contributions.…”

We study the muon g-2 and neutralino dark matter as explained by the MSSM where the squarks and 3rd generation sleptons are decoupled. Particularly, we focus on constraints from current and future dark matter experiments such as PandaX-II and LUX-2016 as well as current bounds from collider searches. Using the constraints on the MSSM from the muon g-2 and DM searches, we study constraints from multilepton + MET searches at 8 TeV LHC, and the prospects for searches at 100 TeV proton-proton collision energies.The European Physical Society Conference on High Energy Physics 5-12 July, 2017 Venice * Speaker.
