Search for Pair Production of Vector-Like Quarks in the bWb‾W channel from Proton–proton Collisions at √s = 13 TeV

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 Tand Yquar...

description 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 Tand Yquarks are assumed to decay exclusively to a Wboson and a bquark. The search is based on events with a single isolated electron or muon, large missing transverse momentum, and at least four jets with large transverse momenta. In the search, a kinematic reconstruction of the final state observables is performed, which would permit a signal to be detected as a narrow mass peak (≈7% resolution). The observed number of events is consistent with the standard model prediction. Assuming strong pair production of the vector-like quarks and a 100% branching fraction to bW, a lower limit of 1295 GeV at 95% confidence level is set on the T and Y quark masses.
