Search for exotic heavy top and bottom quark partners with CMS

Abstract

We present searches for massive top and bottom quark partners at CMS using LHC pp collision data collected at centre-of-mass energy s=8\sqrt{s} = 8 TeV. Such partners can be found in models predicting vector-like quarks to solve the hierarchy problem and stabilize the Higgs boson mass. The searches span a range of final states containing several lepton and jet multiplicities, and limits were set on mass and production cross sections as a function of branching ratios.Comment: Submitted to the proceedings of "The European Physical Society Conference on High Energy Physics - EPS-HEP2013, 18-24 July 2013,Stockholm, Sweden
