Search for pair production of vector-like T and B quarks in single-lepton final states using boosted jet substructure in proton-proton collisions at √s=13 TeV

A search for pair production of massive vector-like T and B quarks in protonproton collisions at √ s = 13 TeV is presented. The data set was collected in 2015 by the CMS experiment at the LHC and corresponds to an integrated luminosity of up to 2.6 fb−1 . The T and B quarks are assumed to decay...
