@misc{10481/96016, year = {2016}, month = {2}, url = {https://hdl.handle.net/10481/96016}, abstract = {A search for vector-like quarks and excited quarks in events containing a top quark and a W boson in the final state is reported here. The search is based on 20.3 fb−1 of proton-proton collision data taken at the LHC at a centre-of-mass energy of 8 TeV recorded by the ATLAS detector. Events with one or two leptons, and one, two or three jets are selected with the additional requirement that at least one jet contains a b-quark. Single-lepton events are also required to contain at least one large-radius jet from the hadronic decay of a high-p T W boson or a top quark. No significant excess over the expected background is observed and upper limits on the cross-section times branching ratio for different vector-like quark and excited-quark model masses are derived. For the excited-quark production and decay to Wt with unit couplings, quarks with masses below 1500 GeV are excluded and coupling-dependent limits are set.}, organization = {CERN for the very successful operation of the LHC}, organization = {ANPCyT, Argentina; YerPhI, Armenia}, organization = {ARC, Australia; BMWFW and FWF, Austria}, organization = {ANAS, Azerbaijan; SSTC, Belarus}, organization = {CNPq and FAPESP, Brazil; NSERC, NRC and CFI, Canada}, organization = {CONICYT, Chile; CAS, MOST and NSFC, China}, organization = {COLCIENCIAS, Colombia; MSMT CR, MPO CR and VSC CR, Czech Republic}, organization = {DNRF, DNSRC and Lundbeck Foundation, Denmark; IN2P3-CNRS, CEADSM/ IRFU, France}, organization = {GNSF, Georgia; BMBF, HGF, and MPG, Germany}, organization = {GSRT, Greece; RGC, Hong Kong SAR, China}, organization = {ISF, I-CORE and Benoziyo Center, Israel; INFN, Italy}, organization = {MEXT and JSPS, Japan; CNRST, Morocco}, organization = {FOM and NWO, Netherlands; RCN, Norway}, organization = {MNiSW and NCN, Poland; FCT, Portugal}, organization = {MNE/IFA, Romania; MES of Russia and NRC KI, Russian Federation}, organization = {JINR; MESTD, Serbia}, organization = {MSSR, Slovakia; ARRS and MIZ S, Slovenia}, organization = {DST/NRF, South Africa; MINECO, Spain}, organization = {SRC and Wallenberg Foundation, Sweden; SERI, SNSF and Cantons of Bern and Geneva, Switzerland}, organization = {MOST, Taiwan; TAEK, Turkey}, organization = {STFC, United Kingdom; DOE and NSF, United States of America}, organization = {Individual groups and members have received support from BCKDF}, organization = {Canada Council, CANARIE, CRC, Compute Canada, FQRNT, and the Ontario Innovation Trust, Canada}, organization = {EPLANET, ERC, FP7, Horizon 2020 and Marie Sk lodowska-Curie Actions, European Union}, organization = {Investissements d'Avenir Labex and Idex, ANR, Region Auvergne and Fondation Partager le Savoir, France}, organization = {DFG and AvH Foundation, Germany}, organization = {Herakleitos, Thales and Aristeia programmes co- nanced by EU-ESF and the Greek NSRF}, organization = {BSF, GIF and Minerva, Israel}, organization = {BRF, Norway}, organization = {The Royal Society and Leverhulme Trust, United Kingdom}, organization = {Crucial computing support from all WLCG partners}, publisher = {Springer}, keywords = {Exotics}, keywords = {Hadron-Hadron scattering}, title = {Search for the production of single vector-like and excited quarks in the Wt nal state in pp collisions at √s = 8 TeV with the ATLAS detector}, doi = {10.1007/JHEP02(2016)110}, author = {Aad, G. and Aguilar Saavedra, Juan Antonio and Atlas Collaboration, /}, }
