“…[48], future collider sensitivities may reach m χ ± 1 1.2-1.3 TeV by analyzing the NC/HW channel at the HL-LHC [101,102], and m χ ± 1 1.4 (3.4) TeV at a future 100 TeV pp collider [103,104]. Besides, the electroweakinos will be able to be probed indirectly [105][106][107][108], e.g., for m χ ± 1 1.7-2.3 TeV at a 100 TeV pp collider. Note that since these evaluations were performed on the simplified models, i.e., the sensitivities would be degraded in realistic setups.…”

The Fermilab Muon g− 2 collaboration recently announced the first result of measurement of the muon anomalous magnetic moment (g− 2), which confirmed the previous result at the Brookhaven National Laboratory and thus the discrepancy with its Standard Model prediction. We revisit low-scale supersymmetric models that are naturally capable to solve the muon g− 2 anomaly, focusing on two distinct scenarios: chargino-contribution dominated and pure-bino-contribution dominated scenarios. It is shown that the slepton pair-production searches have excluded broad parameter spaces for both two scenarios, but they are not closed yet. For the chargino-dominated scenario, the models with $$ {m}_{{\tilde{\mu}}_{\mathrm{L}}}\gtrsim {m}_{{\tilde{\chi}}_1^{\pm }} $$ m μ ˜ L ≳ m χ ˜ 1 ± are still widely allowed. For the bino-dominated scenario, we find that, although slightly non-trivial, the region with low tan β with heavy higgsinos is preferred. In the case of universal slepton masses, the low mass regions with $$ {m}_{\tilde{\mu}} $$ m μ ˜ ≲ 230 GeV can explain the g− 2 anomaly while satisfying the LHC constraints. Furthermore, we checked that the stau-bino coannihilation works properly to realize the bino thermal relic dark matter. We also investigate heavy staus case for the bino-dominated scenario, where the parameter region that can explain the muon g− 2 anomaly is stretched to $$ {m}_{\tilde{\mu}} $$ m μ ˜ ≲ 1.3 TeV.

“…3 the detection reach of Higgsino and Wino from the neutral current (NC) processes (mediated by photon or Z-boson), the charged current (CC) processes (mediated by W -boson), and the combination of these two results. We have seen that the addition of the CC processes improves the detection reach from the previous analysis [14]. From the combined analysis, the bounds at the 5σ (95% C.L.)…”

There are many extensions of the standard model that predict the existence of electroweakly interacting massive particles (EWIMPs), in particular in the context of the dark matter. In this paper, we provide a way for indirectly studying EWIMPs through the precise study of the pair production processes of charged leptons or that of a charged lepton and a neutrino at future 100 TeV collider experiments. It is revealed that this search method is suitable in particular for Higgsino, providing us the 5σ discovery reach of Higgsino in supersymmetric model with mass up to 850 GeV. We also discuss how accurately one can extract the mass, gauge charge, and spin of EWIMPs in our method.

“…While completing this work a preprint appeared on the arXiv [54] where bounds on EW multiplets for the neutral Drell-Yan channel at a future 100 TeV collider were discussed. As we showed however, the charged current channel leads to stronger bounds than the neutral one also for a future 100 TeV collider.…”

Several new physics scenarios, motivated e.g. by dark matter, feature new electroweakly charged states where the lightest particle in the multiplet is stable and neutral. In such cases direct searches at LHC are notoriously difficult, while electroweak precision tests both at hadron and lepton colliders offer the possibility to indirectly probe those states. In this work, we assess the sensitivity of the highluminosity phase of the LHC on new electroweak multiplets via the modification of neutral and charged Drell-Yan processes, and compare the reach of future hadron and lepton colliders presently under consideration. *
