Search for Supersymmetry with a compressed mass spectrum in VBF topology with 1-lepton final states in pp collisions at $\sqrt{s}$ = 13 TeV with CMS

A search for supersymmetric electroweakinos ($\widetilde{\chi}{1}^{\pm}$, $\widetilde{\chi}{2}^{0}$) produced in the vector boson fusion (VBF) topology in proton-proton collisions at $\sqrt{s}$=13 TeV using the full Run 2 data collected by the Compact Muon Solenoid (CMS) detector at the Large Hadron Collider (LHC) is presented. The experimental features of VBF processes provide an increased sensitivity for compressed SUSY, compared to traditional searches. The benchmark model for this search is the R-parity conserving Minimal Supersymmetric Standard Model (MSSM), where the lightest neutralino is the canonical dark matter candidate. This paper presents the search strategy, methodology, and the results on the background estimation using various control regions along with their validation.
