Abstract
We present new limits on resonant t (b) over bar production in p (p) over bar collisions at root s = 1.96 TeV, using 1.9 fb(-1) of data recorded with the CDF II detector at the Fermilab Tevatron. We reconstruct a candidate t (b) over bar mass in events with a lepton, neutrino candidate, and two or three jets, and search for anomalous t (b) over bar production as modeled by W' -> t (b) over bar. We set a new limit on a right-handed W' with standard model-like coupling, excluding any mass below 800 GeV/c(2) at 95% C.L. The cross section for any narrow, resonant t (b) over bar production between 750 and 950 GeV/c(2) is found to be less than 0.28 pb at 95% C. L. We also present an exclusion of the W' coupling strength versus W' mass over the range 300-950 GeV/c(2).
