A Higgsino-like particle is an attractive candidate for the WIMP dark matter. Thanks to the electroweak interaction, the production cross section of the Higgsino at the LHC is rather high. Even for the 1 TeV Higgsino, the LHC run 2 could produce O(100) Higgsino particles. However the huge Standard Model background prevents the Higgsino discovery and the present LHC sensitivity can be even worse than the LEP result in some parameter region. In this talk, I discuss a new search strategy to explore such a parameter region by utilizing exotic tracks from the charged Higgsino: soft displaced track and disappearing track.
