- W4288726095 abstract "In this contribution, a measurement of the top quark pole mass $m_{text{t}}^{text{pole}}$ is presented. Events where a top quark-antiquark pair ($text{t}bar{text{t}}$) is produced in association with at least one additional energetic jet ($text{t}bar{text{t}}$+jet) are analyzed. The data set recorded by the CMS experiment at a center-of-mass energy of 13 TeV, corresponding to a total integrated luminosity of 36.3fb$^{-1}$, is used. Reconstructed events are required to contain two opposite-sign leptons in the final state. Machine learning methods are employed for the reconstruction of the main observable event classification. The normalized $text{t}bar{text{t}}$+jet production cross section as a function of the inverse of the invariant mass of the $text{t}bar{text{t}}$+jet system is measured at the parton level using a likelihood unfolding method. The value for $m_{text{t}}^{text{pole}}$ is extracted by comparing the measurement to next-to-leading order theoretical predictions using two parton distribution functions (PDFs). For a reference set of the ABMP16NLO PDF, the resulting value is $m_{text{t}}^{text{pole}} = 172.94pm1.37$ GeV." @default.
