Abstract: (APS)
The search for the light Higgsino in the minimal supersymmetric standard model is a crucial test of the naturalness criteria in supersymmetry. On the other hand, the direct production of light Higgsinos is also known as one of the most challenging supersymmetry searches at the LHC. The lack of visible leptons due to the compressed spectrum and their small production rates limit their discovery potential in both monojet plus ET events and weak boson fusion (WBF) production. The signal-to-background ratio prediction is usually within the background systematic uncertainties at the LHC. Without color exchange between the beams, e-p colliders are well known to exhibit WBF. Therefore, we search for light Higgsinos at two future e-p colliders at CERN: the Large Hadron electron Collider (LHeC) and the Future Circular Collider in hadron-electron mode (FCC-eh). The light Higgsinos will be produced in pairs through weak boson fusion with controlled background at these colliders. We find that a 95/145 GeV Higgsino can be reached at the 2σ level at the future LHeC/FCC-eh with a luminosity of 3 ab-1, respectively.Note:
- 18 pages, 7 tables, 5 figures. We updated the results at the LHeC and FCC-eh after detector simulation. The relevant Higgs mass spectrum and cuts criteria are added by new tables. The significance is also updated due to new reducible backgrounds have been considered
