The analysis is based on data collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 4:96±0:11 fb-1, and yields the value of δmt = -0:44±0:46 (stat.)±0:27 (syst.) GeV. This result is consistent with equality of particle and antiparticle masses required by CPT invariance, and provides a significantly improved precision relative to existing measurements. © Copyright CERN.Springer Verlag2012Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/15937https://doi.org/10.1007/jhep06(2012)1091126-6708enJournal of High Energy Physicsinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/15937
