Abstract

We present discovery limits for heavy quarks in the Bestest Little Higgs model via pair production at the LHC running at \( \sqrt {s} = 7\;{\text{TeV}} \). We study pair produced heavy toplike quarks decaying to \( b\overline b {W^{ + }}{W^{ - }} \) and \( t\overline t ZZ \) final states and singly produced heavy top-like quarks via t-channel W exchange. These results are compared to currently available limits on heavy top-like quark cross sections from CMS (with 1.14 fb−1 integrated luminosity) for two scenarios of Yukawa couplings. We find that the CMS data limits the mass of the lightest top partner to larger than 413 GeV in the first scenario, where the two lightest top-partners have a small mass splitting, and 364 GeV in the second scenario, where the mass splitting between the two lightest top-partners is larger.
