Abstract

Statistical combinations of searches for charginos and neutralinos using various decay channels are performed using Formula Presented of Formula Presented collision data at Formula Presented 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 Formula Presented, Formula Presented, or Formula Presented bosons are combined to extend the mass reach to the produced supersymmetric particles by 30-100 GeV. The depth of the sensitivity of the original searches is also improved by the combinations, lowering the 95% C.L. cross-section upper limits by 15%-40%.
