Abstract
© 2022 The Author(s)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(1–3.5GeV) mass differences between the lightest neutral and charged states. We point out that using the ETmiss 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.
