A search is presented for the electroweak production of gauginos, the supersymmetric partners of the Standard Model gauge bosons, in a scenario where the mass difference between the lightest supersymmetric particle (LSP) and other light gauginos is small, resulting in decays to virtual W/Z bosons and the LSP. The search is based on 36 fb^-1 of sqrt(s) = 13 TeV data collected by the ATLAS detector at the LHC in 2015 and 2016. The signature is two or three low transverse momentum (pT) charged leptons (e, mu) and large missing transverse energy, which is enhanced by requiring a high pT initial state radiation jet. The use of very low pT leptons poses challenges for triggering, particle identification, and background estimation.
