“…Further potentially relevant searches for light electroweakinos at the LHC -not implemented in SModels-2.2.0have been performed by CMS in [81][82][83][84] and by ATLAS in [85,86]. (For a recent review of searches for electroweakinos at the LHC see [87].) For a variety of reasons many of the obtained limits do not apply to the light electroweakinos considered here: assumed χ 0 1 masses in [81,86] are smaller, assumed chargino masses in [83] are larger, assumed branching fractions for χ 0 i → χ 0 1 + Z /H 125 in [82,85] are larger, and assumed branching fractions for χ 0 i → /τ + ˜ / τ for ˜ , τ searches in [82] are larger than the values obtained here after imposing the constraints implemented in SModels-2.2.0.…”

We study regions in the parameter space of the NMSSM which are able to simultaneously explain the current measured values for the W mass $$M_W$$ M W and the muon anomalous magnetic moment $$a_\mu $$ a μ , and provide a dark matter relic density consistent with the observations as well as constraints from detection experiments. The corresponding regions feature light charginos and sleptons in the 100 GeV–1 TeV range, at least some of them with masses below 175 GeV such such that the electroweakly-interacting SUSY particles generate sufficiently large contributions to $$M_W$$ M W . The LSP is always singlino-like with a mass below 150 GeV, and could possibly remain invisible even at future detection experiments. Decays of electroweak sparticles proceed through cascades via staus and/or sleptons which makes their detection challenging. We propose benchmark points for future searches of such sparticles. The lightest CP-even scalar may have a mass in the 95–98 GeV range with, however, modest signal rates in view of the mild excesses reported in this range at LEP and by CMS at the LHC.
