Description
We present a search for vector-like quarks (VLQ) which decay to third-generation quarks and vector bosons in all hadronic final states. This doublet model search analyzes data from 138 fb^(−1) integrated luminosity at 13 TeV center of mass energy proton-proton collisions collected by the CMS detector. Highly Boosted jets are classified as W, Z, Higgs, top, bottom, and QCD by training a neural network from 262 high level observables that describe the jet substructure and event topology. Events are categorized based upon the leading signal region jets, resulting in 126 possible orthogonal 4-jet signal regions. We estimate the mistagging rates of our jet multi-classifier using an orthogonal QCD-rich control region. We place limits on the existence of VLQs in our data through a fit to HT, the total transverse energy of the event, across all signal regions is performed simultaneously using the Higgs Combine toolbox.
