Description

We propose a new search strategy for higgsinos. Assuming associated production of higgsino-like pairs with a W or Z boson, we search in the missing energy plus hadronically-tagged vector boson channel. We place sensitivity limits for (HL-)LHC searches assuming O(1−3.5 GeV) mass differences between the lightest neutral and charged states. We point out that using the $E_T^\mathrm{miss}$ distribution significantly increases the sensitivity of this search. We find the higgsinos up to 110 (210) GeV can be excluded with 139 (300) fb−1 data. The full data of the HL-LHC will exclude (discover) the higgsinos up to 520 (280) GeV. This work is based on arXiv:2110.04185 published in PLB.
