DESCRIPTION:Speakers: Jeff Shahinian (University of Pennsylvania (US))\n\n
 Supersymmetry remains one of the best motivated and most extensively studi
 ed extensions of the Standard Model. Supersymmetric scenarios with compres
 sed mass spectra offer natural solutions to several Standard Model shortco
 mings\, but are challenging due to their subtle experimental signatures. W
 e present recent searches for higgsino production with the ATLAS experimen
 t using the full Run 2 dataset\, aiming to close the sensitivity gap betwe
 en LEP and the LHC for mass splittings of 0.1–3 GeV. New developments in
  lepton identification—extending down to transverse momenta of 0.5–1 G
 eV—are employed to target promptly decaying higgsinos. Meanwhile\, more 
 long-lived higgsinos are addressed by reconstructing soft pions from their
  decays or chargino tracklets for the most long-lived scenarios. These sea
 rch results establish some of the most stringent mass limits to date on co
 mpressed supersymmetric scenarios.\n \nRefreshments will be served at 10h
