Publisher: | Institute for Ionics | Abstract: | The mass of the top quark is measured in 36.3 fb-1 of LHC proton–proton collision data collected with the CMS detector at s=13TeV . 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). | URI: | https://doi.org/10.1140/epjc/s10052-023-12050-4 https://hdl.handle.net/20.500.13091/4854 |
