Abstract
A generic search for supersymmetric particles with an emphasis on compressed scenariosis performed with √s = 13 TeV proton-proton collisions at the CMS detector using a datasample with integrated luminosity of 138 fb^{−1}. Potential supersymmetric events with initial-state-radiation recoiling against a massive invisible sparticle system are organized using theRecursive Jigsaw Reconstruction method. Events are further categorized by physics objectcounts such as jet multiplicity, lepton multiplicity, b-tags, and kinematic variables that aresensitive to generic compressed sparticle topologies. This work focuses on the following piecesof a larger analysis: the selection of leptons, their efficiency measurement and calibration,and the implementation and optimization of the data driven fit. Finally expected limits witha 95% C.L. are placed on processes that include the production of electroweakinos, sleptons,and stops.
