Statistical combination of ATLAS Run 2 searches for charginos and neutralinos at the LHC

Statistical combinations of searches for charginos and neutralinos using various decay channels are performed using 139 fb−1 of 𝑝⁢𝑝 collision data at √𝑠 =13 TeV with the ATLAS detector at the Large Hadron Collider. Searches targeting pure-wino chargino pair production, pure-wino chargino-neutralino...

Description
Summary:Statistical combinations of searches for charginos and neutralinos using various decay channels are performed using 139 fb−1 of 𝑝⁢𝑝 collision data at √𝑠 =13 TeV 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 𝑊, 𝑍, or ℎ 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%.
