Abstract

Statistical combinations of searches for charginos and neutralinos using various decay channels are performed using 139fb⁻¹ of pp collision data at √s = 13TeV with the ATLAS detector at the Large Hadron Collider. Searches targeting pure-wino chargino pair production pure-wino chargino-neutralino production or higgsino production decaying via Standard Model WZ or h bosons 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 lowering the 95% CL cross-section upper limits by 15%-40%.
