Description
SUSY searches for electroweak (EW) particles at the LHC show consistent excesses between ATLAS and CMS in the channel $pp \to \tilde{\chi}_2^0 \tilde{\chi}_1^\pm \to \tilde{\chi}_1^0 Z^*\,\tilde{\chi}_1^0W^{\pm*}$.
The preferred mass ranges are $m_{\tilde{\chi}_2^0} \sim m_{\tilde{\chi}_1^\pm}$ with $\Delta m := m_{\tilde{\chi}_2^0} - m_{\tilde{\chi}_1^0} \sim 15-20$ GeV. We show that these consistent excesses can be well described within the MSSM and the NMSSM, where the $\tilde{\chi}_1^0$ as DM candidate is in full agreement with all relevant experimental bounds, in particular the DM relic density and the direct detection cross section limits. We discuss how this scenario can be probed at current and future experiments.
