Anomalous resonant production of the fourth-family up-type quarks at the LHC

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 ${t}^{\ensuremath{'}}$ has been studied via the anomalous production subprocess $g{q}_{i}\ensuremath{\rightarrow}{t}^{\ensuremath{'}}$ (where ${q}_{i}=u$, $c$) 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 $\ensuremath{\kappa}/\ensuremath{\Lambda}=0.1\text{ }\text{ }{\mathrm{TeV}}^{\ensuremath{-}1}$ can be reached at $\sqrt{s}=10\text{ }\text{ }\mathrm{TeV}$ and ${L}_{\mathrm{int}}=100\text{ }\text{ }{\mathrm{pb}}^{\ensuremath{-}1}$.
