Abstract: This note reinterprets a search utilising large specific ionisation in the pixel detector and the time-of-flight to the hadron calorimeter of the ATLAS detector at the LHC using an integrated luminosity of 140fb$^{−1}$ of proton-proton collisions at $\sqrt{s}$ = 13 TeV. The signal considered is production of pure wino, anomaly-mediated-SUSY-breaking-like charginos. This search is sensitive to chargino models with lifetimes over O(4)ns for masses up to ≈1.35TeV, and improves upon the existing chargino mass limits at 95 % CL.
