Abstract
An inclusive search for supersymmetry using razor variables is performed in events with four or more jets and no more than one lepton. The results are based on a sample of proton-proton collisions corresponding to an integrated luminosity of 2.3 inverse femtobarns collected with the CMS experiment at a center-of-mass energy of sqrt(s) = 13 TeV. No significant excess over the background prediction is observed in data, and 95% confidence level exclusion limits are placed on the masses of new heavy particles in a variety of simplified models. Assuming that pair-produced gluinos decay only via three-body processes involving third-generation quarks plus a neutralino, and that the neutralino is the lightest supersymmetric particle with a mass of 200 GeV, gluino masses below 1.6 TeV are excluded for any branching fractions for the individual gluino decay modes. For some specific decay mode scenarios, gluino masses up to 1.65 TeV are excluded. For decays to first- and second-generation quarks and a neutralino with a mass of 200 GeV, gluinos with masses up to 1.4 TeV are excluded. Pair production of top squarks decaying to a top quark and a neutralino with a mass of 100 GeV is excluded for top squark masses up to 750 GeV.

Supersymmetry (SUSY) is a proposed extended spacetime symmetry that introduces a bosonic partner for every fermion in the standard model (SM) [1,2,3,4,5,6,7,8,9]
We have presented an inclusive search for supersymmetry in events with no more than one lepton, a large multiplicity of energetic jets, and missing transverse energy
Two background estimation methods are presented, both based on transfer factors between data control regions and the search regions but having very different systematic assumptions: one relying on the simulation and associated corrections derived in the control regions and the other relying on the accuracy of an assumed functional form for the shape of background distributions in the MR and R2 variables
Summary
Supersymmetry (SUSY) is a proposed extended spacetime symmetry that introduces a bosonic (fermionic) partner for every fermion (boson) in the standard model (SM) [1,2,3,4,5,6,7,8,9]. In R-parity [52] conserving SUSY scenarios, the lightest SUSY particle (LSP) is stable and assumed to be weakly interacting. For many of these models, the experimental signatures at the LHC are characterized by an abundance of. We interpret the results of the inclusive search using simplified SUSY scenarios for pair production of gluinos and top squarks. We consider top squark pair production with the top squark decaying to a top quark and the LSP.
