"Precise measurement of the top quark mass in dilepton decays using optimized neutrino weighting." <i>Physics Letters B,</i> 752, (2016) Elsevier: 18-26. https://doi.org/10.1016/j.physletb.2015.10.086.https://hdl.handle.net/1911/103459We measure the top quark mass in dilepton final states of tt¯ events in pp¯ collisions at s=1.96 TeV, using data corresponding to an integrated luminosity of 9.7 fb−1 at the Fermilab Tevatron Collider. The analysis features a comprehensive optimization of the neutrino weighting method to minimize the statistical uncertainties. We also improve the calibration of jet energies using the calibration determined in tt¯→lepton+jets events, which reduces the otherwise limiting systematic uncertainty from the jet energy scale. The measured top quark mass is mt=173.32±1.36(stat)±0.85(syst) GeV.engThis is an open access article under the CC BY license (http://creativecommons.org/licenses/by/4.0/).Journal articlehttps://doi.org/10.1016/j.physletb.2015.10.086
