The measurement uses a sample of top quark pair candidate events containing one isolated electron or muon and at least four jets in the final state. For each event, the mass is reconstructed from a kinematic fit of the decay products to a top quark pair hypothesis. A profile likelihood method is applied using up to four observables per event to extract the top quark mass. The top quark mass is measured to be 171.77±0.37GeV . This approach significantly improves the precision over previous measurements. © 2023, The Author(s).Institute for Ionics2023Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/11658https://doi.org/10.1140/epjc/s10052-023-12050-41434-6044enEuropean Physical Journal Cinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/11658
