Search for vector-like quarks decaying to an all-jets final state using pp collisions at √s = 13 TeV

We present a search for the pair production of vector-like, charge 2/3e quarks “T”, in the all-hadronic final state. Proton-proton collisions at a sqrt(s) = 13 TeV are analyzed using 35.9 fb−1 of data collected by the CMS detector at the Large Hadron Collider during 2016 collisions. We utilize boosted substructure techniques, including N-subjettiness and soft drop mass to identify vector boson hadronic decays. This search optimizes sensitivity to the T->bW decay, but provides interpretations and limits for all possible decays of the T. The results of this cut-based search are complementary to results of a search utilizing the BEST neural-net tagger.
