This search uses proton-proton collision data at a center-of-mass energy of 13 TeV collected by the CMS experiment at the CERN LHC in 2017 and 2018, with a total integrated luminosity of 100 $\\mathrm{fb}^{-1}$. This analysis adopts specific supersymmetric (SUSY) coannihilation scenarios as benchmark signal models, characterized by a next-to-lightest SUSY particle (NLSP) with a mass difference of less than 25 GeV relative to the lightest SUSY particle, assumed to be a bino-like neutralino. In the top squark ($\\tilde{t}$) NLSP model, the NLSP is a long-lived $\\tilde{t}$, while in the bino-wino NLSP scenario, the mass-degenerate NLSPs are a  wino-like long-lived neutralino and a short-lived chargino. The search excludes top squarks with masses less than 400--1100 GeV and wino-like neutralinos with masses less than 220--550 GeV, depending on the signal parameters, including the mass difference, mass, and lifetime of the long-lived particle. It sets the most stringent limits to date for the $\\tilde{t}$ and bino-wino NLSP models.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.166009.v1/t1","@type":"Dataset","description":"The number of observed and predicted background events after the fit to the regions of the search planes.
