“…Combinations of direct detections on a fourth generation of quarks at the LHC [24][25][26][27] and Higgs production cross section and decay width [28,29] have excluded an explanation of the perturbative fourth generation. The two types of vector-like models may leave signatures in the following realms.…”

“…To start with, they are the simplest example of coloured fermions still allowed by experimental data. Indeed, extra quarks with chiral couplings, such as fourth generation quarks, are now excluded [1] by the recent measurements of Higgs-mediated cross sections [2,3], when combined with direct searches at the Large Hadron Collider (LHC) [4,5].…”

“…The pair production of top partners at the LHC has been searched at CMS which sets the t mass bound of 570 GeV or 625 GeV at 95% confidence level (C. L.) assuming purely bW or tZ decay [18,19], while at ATLAS, the bound is 656 GeV at 95% CL for pure bW decay channel [20]. The discovery of Higgs-like boson has made the th decay channel promising and it has been considered in the multi-b jet final state [21][22][23].…”
