The data analysed correspond to an integrated luminosity of 19.7 fb−1 collected with the CMS detector at the LHC in proton-proton collisions at s√=8 TeV. The hadronic decay products of the top quark with high Lorentz boost from the W′ boson decay are detected as a single top flavoured jet. The use of jet substructure algorithms allows the top quark jet to be distinguished from standard model QCD background. Limits on the production cross section of a right-handed W′ boson are obtained, together with constraints on the left-handed and right-handed couplings of the W′ boson to quarks. The production of a right-handed W′ boson with a mass below 2.02 TeV decaying to a hadronic final state is excluded at 95% confidence level. This mass limit increases to 2.15 TeV when both hadronic and leptonic decays are considered, and is the most stringent lower mass limit to date in the tb decay mode. en_US dc.publisher Springer Verlag en_US dc.rights This article is distributed under the terms of the Creative Commons Attribution 4.0 International License, which permits unrestricted use, distribution, and reproduction in any medium, provided you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons license, and indicate if changes were made en_US dc.rights.uri http://creativecommons.org/licenses/by/4.0/ en_US dc.subject Jet substructure en_US dc.subject Hadron-Hadron scattering en_US dc.subject Beyond Standard Model en_US dc.title Search for W′ → tb in proton-proton collisions at √s = 8 TeV en_US dc.type Article en_US kusw.kudepartment Physics and Astronomy en_US dc.identifier.doi 10.1007/JHEP02(2016)122 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
