The data sample analyzed corresponds to an integrated luminosity of 35.9 fb−1. The X5/3 quark is assumed always to decay into a top quark and a W boson. Both the right-handed and left-handed X5/3 couplings to the W boson are considered. Final states with either a pair of same-sign leptons or a single lepton are studied. No significant excess of events is observed above the expected standard model background. Lower limits at 95% confidence level on the X5/3 quark mass are set at 1.33 and 1.30 TeV respectively for the case of right-handed and left-handed couplings to W bosons in a combination of the same-sign dilepton and single-lepton final states. en_US dc.publisher Springer Verlag en_US dc.rights Copyright CERN, for the benefit of the CMS Collaboration. en_US dc.rights.uri http://creativecommons.org/licenses/by/4.0/ en_US dc.subject Beyond Standard Model en_US dc.subject Hadron-Hadron scattering (experiments) en_US dc.subject Top physics en_US dc.title Search for top quark partners with charge 5/3 in the same-sign dilepton and single-lepton final states in proton-proton collisions at √𝑠=13 TeV en_US dc.type Article en_US kusw.kuauthor Sanders, Stephen J. kusw.kudepartment Physics and Astronomy en_US dc.identifier.doi 10.1007/JHEP03(2019)082 en_US kusw.oaversion Scholarly/refereed, publisher version en_US kusw.oapolicy This item meets KU Open Access policy criteria. en_US dc.rights.accessrights openAccess en_US
