Search for pair production of vector-like quarks in the bWb‾W channel from proton–proton collisions at s=13TeV

A search is presented for the production of vector-like quark pairs, TT or YY, with electric charge of 2/3 (T) or −4/3 (Y), in proton–proton collisions at √s = 13 TeV. The data were collected by the CMS experiment at the LHC in 2016 and correspond to an integrated luminosity of 35.8 fb−1. The T an...
