Inclusive search for supersymmetry in pp collisions at $\sqrt{s}$ = 13 TeV using boosted object identification and razor kinematic variables in zero and one lepton final states

A search for supersymmetry is conducted in final states consisting of hadrons and leptons where top quarks or W/Z/Higgs bosons are highly boosted. Proton-proton collision data at a center-of-mass energy of 13 TeV is utilized for the search, gathered by the CMS experiment at the LHC with an integrated luminosity of 138 $fb^{−1}$. Events that show potential for the boosted top quarks and W/Z/Higgs bosons undergoing hadronic or leptonic decays are identified through jet substructure techniques and then analyzed using the razor variables $M_R$ and $R^2$ to identify any potential signal as a peak on a smoothly falling background. The observed event yields found in the signal regions are consistent with the predicted contributions from standard model processes that are made using control samples in the data. This search covers both R-parity conserving and violating supersymmetric models. The study findings are analyzed with respect to the production of gluino pairs, where gluinos disintegrate into top squarks and/or top quarks, or jets and vector bosons, all accompanied by neutralinos. In addition, the research explores direct production of top squark pairs, where top squarks disintegrate into top quarks and neutralinos, bottom squark pairs, where bottom squarks decay into b quarks and neutralinos, and neutralino and charigno pairs, where neutralino and charigno decay into vector bosons and neutralinos. The run2(138 $fb^{−1}$) expected limits shows we could reject gluino mass up to 2 TeV and top squark mass up to 1 TeV. We did unblinding 2017 (41.5 $fb^{−1}$) and observed and expected limits are agreed within 2σ.
