Search for top quark partners with charge 5/3 in the same-sign dilepton and single-lepton final states in proton-proton collisions at √s=13 TeV
A search for the pair production of heavy fermionic partners of the top quark with charge 5/3 (X5/3 ) is performed in proton-proton collisions at a center-of-mass energy of 13 TeV with the CMS detector at the CERN LHC. The data sample analyzed corresponds to an integrated luminosity of 35.9 fb−1...

| description | A search for the pair production of heavy fermionic partners of the top quark
with charge 5/3 (X5/3
) is performed in proton-proton collisions at a center-of-mass energy
of 13 TeV with the CMS detector at the CERN LHC. The data sample analyzed corresponds
to an integrated luminosity of 35.9 fb−1
. The X5/3 quark is assumed always to decay into
a top quark and a W boson. Both the right-handed and left-handed X5/3 couplings to the
W boson are considered. Final states with either a pair of same-sign leptons or a single
lepton are studied. No significant excess of events is observed above the expected standard
model background. Lower limits at 95% confidence level on the X5/3 quark mass are set
at 1.33 and 1.30 TeV respectively for the case of right-handed and left-handed couplings to
W bosons in a combination of the same-sign dilepton and single-lepton final states. |
