Run 2 results of searches for charginos and neutralinos at the ATLAS experiment using a statistical combination

Statistical combinations of searches for charginos and neutralinos using various decay channels are performed using $139\,$fb$^{-1}$ of $pp$ collision data at $\sqrt{s}=13\,$TeV with the ATLAS detector at the Large Hadron Collider. Searches targeting wino-like chargino pair production, wino-like chargino-neutralino production, or higgsino production decaying via Standard Model bosons $W, Z, h$ are combined to extend the mass reach to the produced SUSY particles by $30-100\,$GeV. The depth of the sensitivity of the original searches is also improved by the combinations, improving 95% CL cross-section upper limits by 15-40%.
