Search for vector-like T and B quark pairs in final states with leptons at √s=13 TeV
A search is presented for pair production of heavy vector-like T and B quarks in proton-proton collisions at √ 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...

| description | A search is presented for pair production of heavy vector-like T and B quarks
in proton-proton collisions at √
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 |
