Search for compressed electroweakinos with low-momentum isolated tracks /CMS Collaboration
A search is presented for higgsino dark matter (DM) in final states with a low momentum (soft), isolated track and large missing transverse momentum. In the minimal supersymmetric standard model (MSSM), charginos are most often produced in association with a nearly mass-degenerate neutralino or another chargino, and predominantly decay into the lightest neutralino (DM candidate) and a soft pion. For a mass difference Δm± less than 1 GeV, a discernible displacement of the pion's track with respect to the primary vertex can arise, reaching up to about 1 cm for the smallest allowed Δm±. [...]

Measurement of event shape variables using charged particles inside jets in proton-proton collisions at s = 13 TeV /CMS Collaboration
