[1] Search for supersymmetry with a compressed mass spectrum in the vector boson fusion topology with 1-lepton and 0-lepton final states in proton-proton collisions at sqrt(s) = 13 tev / A. V. Belyaev, E. Boos, M. Dubinin et al. // Journal of High Energy Physics. — 2019. — Vol. 2019, no. 8. — P. 150. A search for supersymmetric particles produced in the vector boson fusion topology in proton-proton collisions is presented. The search targets final states with one or zero leptons, large missing transverse momentum, and two jets with a large separation in rapidity. The data sample corresponds to an integrated luminosity of 35.9 fb−1 of proton-proton collisions at s√= 13 TeV collected in 2016 with the CMS detector at the LHC. The observed dijet invariant mass and lepton-neutrino transverse mass spectra are found to be consistent with the standard model predictions. Upper limits are set on the cross sections for chargino (χ˜±1) and neutralino (χ˜02) production with two associated jets. For a compressed mass spectrum scenario in which the χ˜±1 and χ˜02 decays proceed via a light slepton and the mass difference between the lightest neutralino χ˜01 and the mass-degenerate particles χ˜±1 and χ˜02 is 1 (30) GeV, the most stringent lower limit to date of 112 (215) GeV is set on the mass of these latter two particles.
