Abstract: Low-scale gaugino mediation predicts that gauginos are significantly heavierthan scalar superpartners. In order of increasing mass the lightestsuperpartners are the gravitino, right-handed sleptons and left-handed sleptonsno light neutralino!. This implies that squark decay chains pass through oneor more sleptons and typical final states from squark and gluino production atthe LHC include multiple leptons. In addition, left-handed staus have largebranching fractions into right-handed staus and the Higgs. As an example, wecompute the spectrum of low-scale deconstructed gaugino mediation. In thismodel gauginos acquire masses at tree level at 5 TeV while scalar masses aregenerated radiatively from the gaugino masses.
