Considering the present limits on their masses from the Tevatron experiments, the fourth-family quarks are expected to have masses larger than the top quark. Because of their expected large masses, they could have different dynamics than the third-family quarks of the standard model. The resonant production of the fourth-family up-type quark t′ has been studied via the anomalous production subprocess gqi→t′ (where qi=u, c) at the LHC, with center-of-mass energies of 10 TeV and 14 TeV. The signatures of such a process are discussed within the standard model decay modes. The sensitivity to the anomalous coupling κ/Λ=0.1TeV-1 can be reached at s=10TeV and Lint=100pb-1. © 2009 The American Physical Society.
