The data set used in the analysis corresponds to an integrated luminosity of 20.2 fb −1 . The large multi-jet background is modelled using a data-driven method. The top-quark mass is obtained from template fits to the ratio of the three-jet to the dijet mass. The three-jet mass is obtained from the three jets assigned to the top quark decay. From these three jets the dijet mass is obtained using the two jets assigned to the W boson decay. The top-quark mass is measured to be 173.72 ± 0.55 (stat.) ± 1.01 (syst.) GeV. | URI: | https://hdl.handle.net/10316/108255 | DOI: | 10.1007/JHEP09(2017)118 | Rights: | openAccess |
