Query: Higgsino Dark Matter or Not: Role of Disappearing Track Searches at the
  LHC and Future Colliders   Higgsino in supersymmetric standard models is known to be a promising
candidate for dark matter in the Universe. Its phenomenological property is
strongly affected by the gaugino fraction in the Higgsino-like state. If this
is sizable, in other words, if gaugino masses are less than ${\cal O}(10)$ TeV,
we may probe the Higgsino dark matter in future non-accelerator experiments
such as dark matter direct searches and measurements of electric dipole
moments. On the other hand, if gauginos are much heavier, then it is hard to
search for Higgsino in these experiments. In this case, due to a lack of
gaugino components, the mass difference between the neutral and charged
Higgsinos is uniquely determined by electroweak interactions to be around $350$
MeV, which makes the heavier charged state rather long-lived, with a decay
length of about $1$ cm. In this letter, we argue that a charged particle with a
flight length of ${\cal O}(1)$ cm can be probed in disappearing-track searches
if we require only two hits in the pixel detector. Even in this case, we can
reduce background events with the help of the displaced-vertex reconstruction
technique. We study the prospects of this search strategy at the LHC and future
colliders for the Higgsino dark matter scenario. It is found that an almost
pure Higgsino is indeed within the reach of the future $33$ TeV collider
experiments. We then discuss that the interplay among collider and
non-accelerator experiments plays a crucial role in testing the Higgsino dark
matter scenarios. Our strategy for disappearing-track searches can also enlarge
the discovery potential of pure wino dark matter as well as other
electroweak-charged dark matter candidates.
