With the parton distribution function set NNPDF2.3, a pole mass of 176.7−3.4 +3.8 GeV is obtained when constraining αS at the scale of the Z boson mass, mZ, to the current world average. Alternatively, by constraining mt pole to the latest average from direct mass measurements, a value of αS(mZ)=0.1151−0.0032 +0.0033 is extracted. This is the first determination of αS using events from top-quark production. © 2013 The AuthorsElsevier B.V.2014Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/15639https://doi.org/10.1016/j.physletb.2013.12.0090370-2693enPhysics Letters, Section B: Nuclear, Elementary Particle and High-Energy Physicsinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/15639
