Description

We present a search for the electroweak production of a vector-like top quark partner T of charge + 2/3 in association with a standard model top or bottom quark, using proton-proton collision data at √s=13 TeV collected by the CMS Experiment at the CERN LHC. Our search targets T quarks decaying to a top quark and a Higgs or Z boson in a fully hadronic final state. For a T quark with mass above 1 TeV the daughter top quark and Higgs/Z boson are highly Lorentz-boosted and can appear together as a single hadronic jet. The top quark and Higgs/Z boson are identified using b-tagging and jet substructure techniques, which also acts to suppress the standard model backgrounds.
