We present results of searches for massive top and bottom quark partners using proton-­proton collision data collected with the CMS detector at the CERN LHC at a center-of­-mass energy of 8 and 13 TeV. These fourth-­generation vector-­like quarks are postulated to solve the Hierarchy problem and stabilize the Higgs mass, while escaping constraints on the Higgs cross section measurement. The vector­-like quark can be produced singly or in pair and their decays result in a variety of final states, containing top and bottom quarks, gauge and Higgs bosons. We search using several categories of reconstructed objects, from multi-leptonic to fully hadronic final states. We set exclusion limits on both the vector-­ like quark mass and cross sections, for combinations of the vector-­like quark branching ratios.
