We present new limits on resonant tb̅ production in pp̅ collisions at sqrt[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 tb̅ mass in events with a lepton, neutrino candidate, and two or three jets, and search for anomalous tb̅ production as modeled by W′→tb̅ . We set a new limit on a right-handed W′ with standard model-like coupling, excluding any mass below 800 GeV/c2 at 95% C.L. The cross section for any narrow, resonant tb̅ production between 750 and 950 GeV/c2 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/c2.
