Abstract
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$$ \sqrt{s} $$ = 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 χ˜1±$$ \left({\tilde{\upchi}}_1^{\pm}\right) $$ and neutralino χ˜20$$ \left({\tilde{\upchi}}_2^0\right) $$ production with two associated jets. For a compressed mass spectrum scenario in which the χ˜1±$$ {\tilde{\upchi}}_1^{\pm } $$ and χ˜20$$ {\tilde{\upchi}}_2^0 $$ decays proceed via a light slepton and the mass difference between the lightest neutralino χ˜10$$ {\tilde{\upchi}}_1^0 $$ and the mass-degenerate particles χ˜1±$$ {\tilde{\upchi}}_1^{\pm } $$ and χ˜20$$ {\tilde{\upchi}}_2^0 $$ 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.
