abstract = {This paper presents a search for direct electroweak gaugino
or gluino pair production with a chargino nearly
mass-degenerate with a stable neutralino. It is based on an
integrated luminosity of 36.1 fb$^{−1}$ of pp collisions
at $ \sqrt{s}=13 $ TeV collected by the ATLAS experiment at
the LHC. The final state of interest is a disappearing track
accompanied by at least one jet with high transverse
momentum from initial-state radiation or by four jets from
the gluino decay chain. The use of short track segments
reconstructed from the innermost tracking layers
significantly improves the sensitivity to short chargino
lifetimes. The results are found to be consistent with
Standard Model predictions. Exclusion limits are set at 95\%
confidence level on the mass of charginos and gluinos for
different chargino lifetimes. For a pure wino with a
lifetime of about 0.2 ns, chargino masses up to 460 GeV are
excluded. For the strong production channel, gluino masses
up to 1.65 TeV are excluded assuming a chargino mass of 460
GeV and lifetime of 0.2 ns.},
