Description

We present searches for pair-production of fourth generation t(prime) quarks in their decays to Wq. We analyze 4.6 fb-1 and 4.3 fb-1 of data collected by the CDF and D0 detectors, respectively, at the Fermilab Tevatron collider at a centre-of-mass energy of √s = 1.96 TeV.We reconstruct the mass of the heavy quark and perform a two-dimensional-fit to the observed (HT,Mreco) distribution to discriminate the new physics signal from standard model backgrounds. As no significant excess of events is observed, we exclude a fourth-generation t(prime) quark with a mass below 335 (296) GeV at 95%CL at CDF (D0).
