  "abstract": "We study the disappearing-track signature of a spin-1 minimal dark matter candidate transforming in the real five-dimensional representation of $SU(2)_L$ with vanishing hypercharge. Radiative electroweak corrections induce a compressed mass spectrum among the multiplet components, allowing the singly charged state $V^\\pm$ to attain a macroscopic lifetime and decay via $V^\\pm \\to V^0 π^\\pm$ inside tracking detectors. We recast the ATLAS search for disappearing tracks with the full Run-2 dataset of $137\\text{ fb}^{-1}$, originally targeted at long-lived charginos, computing the tracklet reconstruction probability analytically from the published efficiency so that the full lifetime range is covered. The procedure reproduces the ATLAS limits for pure winos within $6\\%$ in mass. The Run-2 data exclude quintuplet masses up to $1080\\text{ GeV}$ for proper decay lengths $cτ\\simeq 250\\text{ mm}$, and $M_V < 630\\text{ GeV}$ for a mass splitting of $166\\text{ MeV}$. For the radiative mass splitting predicted by the model with a small Higgs-portal coupling, masses between $120\\text{ GeV}$ and $240\\text{--}300\\text{ GeV}$ are excluded. With $3\\text{ ab}^{-1}$ and a Run-2-like analysis, the sensitivity would extend to $1750\\text{ GeV}$ for vanishing background and to $1530\\text{ GeV}$ for a linear extrapolation of the instrumental background.",
