Abstract
We present new limits on resonant tb&#773; production in pp&#773; collisions at √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 tb&#773; mass in events with a lepton, neutrino candidate, and two or three jets, and search for anomalous tb&#773; production as modeled by W′→tb&#773; . 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 tb&#773; 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 300950  GeV/c2.
