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(') has been studied via the anomalous production subprocess gq(i)-> t(') (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 kappa/Lambda=0.1 TeV-1 can be reached at s=10 TeV and L-int=100 pb(-1).
