A search for the electroweak production of pairs of charged sleptons or charginos decaying into two-lepton final states with missing transverse momentum is presented. Two simplified models of R-parity-conserving supersymmetry are considered: direct pair-production of sleptons (ℓ∼ℓ∼)(ℓ∼ℓ∼), with each decaying into a charged lepton and a χ∼10χ∼​10​ neutralino, and direct pair-production of the lightest charginos (χ∼1±χ∼1∓)(χ∼​1±​χ∼​1∓​), with each decaying into a W-boson and a χ∼10χ∼​10​. The lightest neutralino (χ∼10)(χ∼​10​) is assumed to be the lightest supersymmetric particle (LSP). The analyses target the experimentally challenging mass regions where m(ℓ∼)−m(χ∼10)m(ℓ∼)−m(χ∼​10​) and m(χ∼1±)−m(χ∼10)m(χ∼​1±​)−m(χ∼​10​) are close to the W-boson mass (‘moderately compressed’ regions).
