Current Large Hadron Collider (LHC) analyses are blind to compressedsupersymmetry (SUSY) models with sleptons near the lightest super partner (LSP)in mass: $m_{\tilde{l}} - m_{\tilde{\chi}_1^0} \equiv \Delta m \lesssim 60$GeV. We present a search sensitive to the very compressed range $3~\text{GeV} <\Delta m < 24~\text{GeV}$ using the channel $p p \rightarrow \tilde{l}^+\tilde{l}^- +\rm{jet} \rightarrow$ $l^+ l^- \tilde{\chi}_1^0 \tilde{\chi}_1^0+\rm{jet}$ with soft same-flavor leptons and one hard jet from initial stateradiation ($p_{\rm T}^j >100$ GeV). The sleptons recoil against the jetboosting them and their decay products, making the leptons detectable andproviding substantial missing transverse momentum. We use the kinematicvariable $m_{\rm T 2}$ along with a different-flavor control region to reducethe large standard model backgrounds and control systematic uncertainty. Wefind the analysis should allow LHC14 with $100~\text{fb}^{-1}$ to search fordegenerate left-handed selectrons and smuons in the compressed region up to$m_{\tilde{l}_L} \lesssim 150$ GeV. In addition, it should be sensitive to$m_{\tilde{l}_L} \lesssim 110$ GeV for the very challenging case ofauto-concealed SUSY, in which left-handed sleptons decay to the Kaluza-Kleintower of a modulino LSP which lives in $d=6$ extra dimensions. In both thecompressed spectrum and auto-concealed SUSY scenarios this analysis will needmore data to improve on LEP2 limits for right-handed sleptons due to theirsmaller cross sections.
