摘要

A top quark mass measurement is performed using

35.9 {fb}^{- 1}

of LHC proton–proton collision data collected with the CMS detector at

\sqrt{s} = 13 TeV

. The measurement uses the

t \bar{t}

all-jets final state. A kinematic fit is performed to reconstruct the decay of the

t \bar{t}

system and suppress the multijet background. Using the ideogram method, the top quark mass (

m_{t}

) is determined, simultaneously constraining an additional jet energy scale factor (

JSF

). The resulting value of

m_{t} = 172.34 \pm 0.20 (stat+JSF) \pm 0.70 (syst) GeV

is in good agreement with previous measurements. In addition, a combined measurement that uses the

t \bar{t}

lepton+jets and all-jets final states is presented, using the same mass extraction method, and provides an

m_{t}

measurement of

172.26 \pm 0.07 (stat+JSF) \pm 0.61 (syst) GeV

. This is the first combined

m_{t}

extraction from the lepton+jets and all-jets channels through a single likelihood function.
