The analysis uses proton-proton collision data collected with the CMS detector at s=13 TeV, corresponding to an integrated luminosity of 138 fb−1. No significant deviation from background expectations is observed. Upper limits at 95% confidence level on the product of cross section, branching fraction to dimuons, acceptance, and efficiency, from 0.2 to 2 fb, are set for Z′ boson masses between 125 and 350 GeV. Process-dependent products of acceptance and efficiency, and model-independent limits on the signal yield are provided. These are the only results to date in the 125–200 GeV mass range and the most stringent for b quark fusion production modes in the 200–350 GeV range, complementing inclusive Z′ boson searches. © The Author(s) 2026.Springer Science and Business Media Deutschland GmbH2026Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/10185https://doi.org/10.1007/jhep07(2026)0081029-8479enJournal of High Energy Physicsinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/10185
