Description
Result of the top quark mass and nuisance parameters from the 5D profile likelihood fit in the lepton+jets channel
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 = 13 TeV. 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 ± 0.37 GeV. This approach significantly improves the precision over previous measurements
