Measurement of the top quark mass using a profile likelihood approach with the lepton + jets final states in proton–proton collisions at $$\sqrt{s}=13\,\text {Te}\hspace{-.08em}\text {V}$$
Journal Article·· European Physical Journal. C, Particles and Fields (Online)
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 $$\sqrt{s}=13\,\text {Te}\hspace{-.08em}\text {V}$$. 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.
