Search for supersymmetry with jets and missing transverse momentum in pp collisions at 13 TeV at CMS

We present the results of searches for R-parity-conserving Supersymmetry in all-hadronic final states based on a dataset of 12.9~\fb{} of 13~TeV proton-proton collisions recorded in 2016 by the CMS experiment at LHC. The results of three searches~(\HT/\MHT{}, \mtt{} and \alphaT{}) are detailed. The backgrounds to these searches are estimated directly in the data. No significant excess is recorded with respect to the background estimations. Exclusion limits are set, at 95\pct confidence level, on simplified models. Depending on the model, gluino masses are excluded up to 1.7~TeV, top squarks up to 900~GeV, and neutralinos (here considered the lightest Supersymmetric particle) up to 1.2~TeV.
