The fourth family quarks are expected to have mass larger than the top quark considering the results from recent studies on the allowed parameter space. They could also have different dynamics than the quarks of three families of the standard model. The single production of the fourth family up-type quark t%26apos; is studied via the anomalous production process pp -%26gt; t%26apos;VX (where V = g, Z, gamma) at the LHC with the center of mass energy of 7 and 14 TeV. The signatures of such process are discussed within both the SM and the anomalous decay modes of t%26apos; quarks. The sensitivity to anomalous coupling kappa/Lambda = 0.004 TeV-1 can be reached at root s = 14 TeV and L-int = 100 pb (1).
