Search for supersymmetry in final states with disappearing tracks in proton-proton collisions at 13 TeV — •Samuel Bein, Viktor Kutzner, Malte Mrowietz, Peter Schleper, Alexandra Tews, and Moritz Wolf — Universität Hamburg, Hamburg, Germany

We report the results of a search for charged, semi-stable, supersymmetric particles in final states with one or more disappearing tracks embedded within a range of final states characterized by varying numbers of jets, b-tagged jets, electrons, and muons. The transverse length of signal candidate tracks is used to target various lifetimes associated with wino-like and Higgsino-like charginos in the MSSM, as well as semi-stable charged particles with longer lifetimes. The hit-averaged deposited energy associated with signal candidates traversing the pixel tracker is used to increase sensitivity to particles with large mass or small boost. The search uses a sample of proton-proton collisions at sqrt(s)=13 TeV collected between 2016 and 2018, corresponding to an integrated luminosity of 136 fb$^{-1}$. Limits on the pair production of gluinos and squarks are obtained in the framework of simplified and full-spectrum SUSY models.
