A search for the pair-production of vector-like T and B quarks decaying into an all-hadronic final state is presented. Data corresponding to 35.9 fb−1 collected by CMS during 2016 at the LHC are analyzed. The analysis makes use of jet substructure and mass drop techniques to identify jets coming from boosted W decays, and is optimized for the discovery of a T quark decaying to a bottom quark and a W boson. The scalar sum of jet momenta is tested for the presence of signal, and upper limits at the 95% confidence level are established on the existence of the T and B for masses less than 1040 GeV and 1070 GeV respectively.
