Yetkin, Elif Aslı2020-06-172020-06-172018-08-281029-8479https://hdl.handle.net/11411/2236https://doi.org/10.1007/JHEP08(2018)177A search is presented for pair production of heavy vector-like T and B quarks in proton-proton collisions at A root s = 13 TeV. The data sample corresponds to an integrated luminosity of 35.9 fb(-1), collected with the CMS detector at the CERN LHC in 2016. Pair production of T quarks would result in a wide range of final states, since vector-like T quarks of charge 2e/3 are predicted to decay to bW, tZ, and tH. Likewise, vector-like B quarks are predicted to decay to tW, bZ, and bH. Three channels are considered, corresponding to final states with a single lepton, two leptons with the same sign of the electric charge, or at least three leptons. The results exclude T quarks with masses below 1140-1300 GeV and B quarks with masses below 910-1240 GeV for various branching fraction combinations, extending the reach of previous CMS searches by 200-600 GeV.eninfo:eu-repo/semantics/openAccessHadron-Hadron scattering (experiments)vector-like quarksArticle2-s2.0-8505283975510.1007/JHEP08(2018)177Q1WOS:000443527200005
