Search for pair production of vector-like T and B quarks in single-lepton final states using boosted jet substructure in proton-proton collisions at √s=13 TeV
A search for pair production of massive vector-like T and B quarks in protonproton collisions at √ s = 13 TeV is presented. The data set was collected in 2015 by the CMS experiment at the LHC and corresponds to an integrated luminosity of up to 2.6 fb−1 . The T and B quarks are assumed to decay...

| description | A search for pair production of massive vector-like T and B quarks in protonproton collisions at √
s = 13 TeV is presented. The data set was collected in 2015 by
the CMS experiment at the LHC and corresponds to an integrated luminosity of up to
2.6 fb−1
. The T and B quarks are assumed to decay through three possible channels into
a heavy boson (either a W, Z or Higgs boson) and a third generation quark. This search
is performed in final states with one charged lepton and several jets, exploiting techniques
to identify W or Higgs bosons decaying hadronically with large transverse momenta. No
excess over the predicted standard model background is observed. Upper limits at 95%
confidence level on the T quark pair production cross section are set that exclude T quark
masses below 860 GeV in the singlet, and below 830 GeV in the doublet branching fraction
scenario. For other branching fraction combinations with B(T → tH) +B(T → bW) ≥ 0.4,
lower limits on the T quark range from 790 to 940 GeV. Limits are also set on pair
production of singlet vector-like B quarks, which can be excluded up to a mass of 730 GeV.
The techniques showcased here for understanding highly-boosted final states are important
as the sensitivity to new particles is extended to higher masses |
