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 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 $$\sqrt{s}=$$ 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 ($$\widetilde\chi_1^\pm$$) and neutralino ($$\widetilde\chi_2^0$$) production with two associated jets. For a compressed mass spectrum scenario in which the $$\widetilde\chi_1^\pm$$ and $$\widetilde\chi_2^0$$ decays proceed via a light slepton and the mass difference between the lightest neutralino $$\widetilde\chi_1^0$$ and the mass-degenerate particles $$\widetilde\chi_1^\pm$$ and $$\widetilde\chi_2^0$$ 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.
